ÁProblem and page number. References the current document. In this example, 1.1
indicates problem 1, page 1 of the active document.
ÂSettings. Click here to view or change Document settings.
ÃZoom/Boldness. When working with a document in Handheld page size, use the
Zoom scale to zoom the active document in or out from 10% to 500%. To set a
zoom, type a specific number, use the + and - buttons to increase or decrease by
increments of 10%, or use the drop-down box to choose preset percentages.
When working with a document in Computer page size, use the Boldness scale to
increase or decrease the boldness of text and line thickness within applications. To
set the boldness, type a specific number, use the + and - buttons to increase or
decrease by increments of 10%, or use the drop-down box to choose preset
percentages.
In the Review Workspace, the status bar information changes, depending on the view

4. Click Quit Now to close the software immediately. You will be prompted to save
any open documents. When you restart the software, the language change is
effective.
—or—
Click Quit Later to continue your work. The language change is not applied until you
close and restart the software at a later time.
Note: If you select Simplified Chinese or Traditional Chinese as the language in the
TI-Nspire™ software, you should see Chinese characters in the menus and dialogues. If
your computer uses the Windows® XP operating system and you do not see Chinese
characters, you may need to install the Windows® XP East Asian Language Support
package.
Connecting to the Network
Connection from student computers to teacher computers is through the school
network.
It’s best if the teacher computer has a wired connection, but the network administrator
will know which connection is best for your environment.
Student connections can be wired or wireless.
Teacher wired and students wired Teacher wired and students wireless
Once the school network administrator has provided network access, you are
automatically recognized and connected to the network when you open the software.
Verifying Connectivity
To verify your connection:
1. In the Class Workspace, click File > Settings > Teacher Preferences.
The Teacher Preferences dialogue box opens.
2. View the IP Addresses in the Network Settings area. If the host name and IP
address are present, you are connected and able to broadcast.
Note: If the IP address is missing, contact your Network Administrator.
Helping Students Log In
Students using TI-Nspire™ CX Student Software or TI-Nspire™ CX CAS Student Software
can log in to active classes if they have a user name and password.
Note: For information about how to create a class, start a class, build a class roster,
and create a user name and password for each student, see Using the Class
Workspace.
There are two ways for students to log in:
• Using the class name, which is the preferred method.
• Using the host name or IP address. Use this method when:
- Broadcasting multiple addresses (such as wired and wireless) and one address
is preferred. If your IT administrator has a preferred address, it will be
provided. Otherwise, the host name or any other available IP address can be
used.
- The class name does not appear in the Select Class and Login dialogue box.
This occurs when there is a timing issue between the network sending the
class name and software receiving it.
Getting Started with TI-Nspire™ Navigator NC Teacher Software 7
8 Getting Started with TI-Nspire™ Navigator NC Teacher Software
- If there are several classes running at the same time that have identical
names, such as "Algebra 1." The student will not know which class to select.
Best practice is to append a unique identifier such as the course ID or the
teacher name to the class name.
Providing Students with a Host Name or IP Address
Complete the following steps to locate host name or IP address.
1. In the Class Workspace, click File > Settings > Teacher Preferences.
The Teacher Preferences dialogue box opens.
The host name and IP address are on the same line. You may be broadcasting several
addresses. If your network administrator has not specified a preference, use any
address.
2. Provide students either the host name or the IP address, but not both.
Host Name IP Address
3. Click OK.
The Teacher Preferences dialogue box closes.
Logging in Using Class Name
Ask students to complete the following steps to log in using a class name. Students
can log in after you start the class.
1. Click Tools > Login to a TI-Nspire Navigator Session.
The Select Class and Login dialogue box opens.
2. Click ¤to open the Class drop-down list, and then select a class.
3. Type your user name and password.
Note: User names and passwords are defined when a teacher creates the class
roster. Teachers can either provide a password or allow students to create their
own.
4. Click OK.
The "You are logged into class" confirmation message is displayed.
5. Click OK to close the dialogue box.

Getting Started with TI-Nspire™ Navigator NC Teacher Software 13
Tracking and Reporting System Use
Schools participating in research-based programmes or schools receiving money from
funding initiatives must track student use of the TI-Nspire™ Navigator™ systems and
provide reports for auditing purposes.
To automatically track student usage of the TI-Nspire™ Navigator™ systems, a folder
named "SessionLogs" is created within the appropriate TI-Nspire™ Navigator™
software folder on the teacher's computer when the software is installed. The
software generates the files needed for tracking activity types, attendance, class
session information and activities that take place during a class session. The files are
dependent on each other and must be kept together in the SessionLogs folder so that
usage information is tracked and reported accurately.
The system automatically captures system usage data and appends the information for
each new class session in the appropriate file. If the system does not find a
SessionLogs folder, data is not tracked.
Managing Session Logs
The system automatically generates the following comma-separated variable (csv)
files and stores them in the SessionLogs folder. Each time you start the TI-Nspire™
software, logs are appended to the previous day’s log to keep a complete record.
•Activities.csv file. Activities that take place during class sessions are recorded in
this file.
•ActivityTypes.csv file. This file is the lookup table that the system references when
generating a usage report.
•Attendance.csv file. Information for each student who logs into a session is
recorded in this file.
•ClassSession.csv file. Information for all class sessions is recorded in this file.
Using the Activities File
The system records information about the activities that took place during the class
session in this file. Information includes:
•ClassSessionID. Class ID number unique to the funding programme.
•ClassName. Name of the class as defined in the software.
•ActivityTypeID. Type of activity that took place during the class. The ID correponds
to the activity types defined in the Activity Type file.
•ActivityDetail. Additional data about the activity type if available.
•ActivityStart. Time the activity started.
•ActivityEnd. Time the activity ended.
•NumStudent. Number of students who participated in this activity.

Using the Attendance File
The system records information for each student who logged into a session in the
Attendance file. Information includes:
•Class ID. The Class ID number unique to the funding programme.
•Class Name. Name of the class as defined in the software.
•Last Name. Last name of the student.
•First Name. First name of the student.
•Date and Time. Date and time when student logged in. Used to identify students
who logged in on time versus late.
•Student ID. The ID of the student.
Using the Class Session File
The system records information for each class session by Class ID. Information
includes:
•ClassSessionID. The Class ID number unique to the funding programme.
•ClassName. Name of the class as defined in the software.
•Start. Time the class started as recorded when the teacher clicks Begin Class.
•End. Time the class ended as recorded when the teacher clicks End Class.
•NumStudent. Number of students who logged in during the class session.
•ClassSectionName. Name of the class section.
•QuickPollTotalTime. Amount of time student spend on Quick Polls.
Managing Log Files
Session log files are managed automatically based upon their file size each time the
TI-Nspire™ is turned off. If the size of any one of the files is greater than 1 MB during
shutdown, a backup of each file is created in the SessionLogs folder with the following
names:
• Activities-bak.csv
• ActivityTypes-bak.csv
• Attendance-bak.csv
• ClassSession-bak.csv
Note: If a backup file already exists, it will be overwritten with a newer version.
The next time the TI-Nspire™ is turned on, four new, empty log files will be created.
Packaging and Sending Session Logs
The district administrator must report usage to the funding source for auditing
purposes at regular intervals. When files are requested, teachers can easily package
the session files into a zip file and send the file to the administrator. The zip file
preserves the format and dependencies of the activity files, and includes a default file
name that identifies the zip file for the administrator.
Complete the following steps to package the files in the SessionLogs folder into a zip
file and send the file to the administrator.
1. From the Content Workspace, click File > Package Session Logs.
Tracking and Reporting System Use 16
17 Tracking and Reporting System Use
Note: This menu item is only available if the SessionLogs folder was created.
The previous session log content is saved. Subsequent session data will append to
the existing files in the same folder as the previous sessions.
The software packages the files into a zip file and assigns a default name (TI_PKG_
SessionLogs_MMDDYYYY). The Logs package dialogue box opens.
2. Click Yes to go to the location where the zip file was saved.
Windows® Explorer (or Finder) opens. The zip file is saved in the same location as
the SessionLogs folder. For example, if you have TI-Nspire™ Navigator™ NC
Teacher Software, the SessionLogs folder is stored in the following location:
PC:
...\My Documents\My TI-Nspire™ Navigator™ NC Teacher Software\
Mac®:
.../Documents/My TI-Nspire™ Navigator™ NC Teacher Software/
3. Email the zip file to the administrator.
Data is appended to the existing file each time you start a new session. If you no
longer need the information after the files are sent to the administrator, remove
them from the SessionLogs folder and keep the zip file. The system will generate
new files the next time you start a new session.

Working with TI-Nspire™ Documents
All work that you create and save using TI-Nspire™ applications is stored as a
document, which you can share with others using TI-Nspire™ software and with those
using handhelds. There are two types of documents:
• TI-Nspire™ document (.tns file)
• PublishView™ document (.tnsp file)
TI-Nspire™ Documents
A TI-Nspire™ document consists of one or more problems. Each problem can contain
one or more pages. A single page is displayed in the work area. All work occurs in the
applications within pages.
Because the TI-Nspire™ software and handhelds share the same functionality, you can
transfer TI-Nspire™ documents between computers and handhelds. When you create a
document, you select one of two page sizes.
•Handheld. Size: 320 ×217 pixels. This size allows documents to be viewed on all
platforms. The content will be scaled when viewed on a tablet or larger screen.
•Computer. Size: 640 ×434 pixels. The content will not be scaled when viewed on
smaller platforms. Some content may not be visible on a handheld device.
You can convert a document from one page size to the other any time.
PublishView™ Documents
PublishView™ documents can be printed on a standard piece of paper or published to a
website or blog. PublishView™ documents can include formatted text, images and
hyperlinks as well as all TI-Nspire™ applications.
For more information, see Working with PublishView™ Documents.
Creating a New TI-Nspire™ Document

Working with PublishView™ Documents
Use the PublishView™ feature to create and share interactive documents with teachers
and students. You can create documents that include formatted text, TI-Nspire™
applications, images, hyperlinks, links to videos and embedded videos in a format that
is suitable for printing on a standard piece of paper, publishing to a website or blog, or
for use as an interactive worksheet.
PublishView™ features provide layout and editing features for presenting maths and
science concepts in a document where TI-Nspire™ applications can be interactively and
dynamically linked with supporting media, enabling you to bring the document to life.
Using the PublishView™ feature:
• Teachers can create interactive activities and assessments used on screen.
• Teachers can create printed materials to complement documents used on
TI-Nspire™ handhelds.
• When working with lesson plans, teachers can:
- Create lesson plans from existing handheld documents or convert lesson plans

- Link to related lesson plans or documents.
- Embed explanatory text, images, video and links to web resources.
- Build or interact with TI-Nspire™ applications directly from the lesson plan.
• Students can create reports or projects such as lab reports containing data
playback, curve fits, pictures and video—all on the same sheet.
• Students can print and turn in assignments on a standard piece of paper.
• Students taking exams can use one tool to create a document that contains: all
problems on the exam, text, images, hyperlinks, or videos, interactive TI-Nspire™
applications, screen shots and layout options needed to print a document.
Note: PublishView™ documents can be exchanged using the TI-Nspire™ Navigator™ NC
system. PublishView™ documents can reside in the Portfolio Workspace and TI-
Nspire™ questions within a PublishView™ document can be automatically graded by

About PublishView™ Documents
When working with PublishView™ documents, it is important to keep the following
points in mind:
• PublishView™ documents are saved as .tnsp files, which distinguishes them from
TI-Nspire™ documents (.tns files).
• When inserting PublishView™ objects into a document, the text, image, hyperlink
or embedded video are contained in boxes that can be moved and resized.
• When you insert TI-Nspire™ applications, they work the same way as pages in a
TI-Nspire™ document.
• In a PublishView™ document, objects can overlap each other and you can control
which object is on top or bottom.
• Objects can be placed and positioned in a PublishView™ document in a free-form
fashion.
• You can convert an existing TI-Nspire™ document to a PublishView™ document
(.tnsp file).
• When you convert a PublishView™ document to a TI-Nspire™ document (.tns file),
TI-Nspire™ applications are converted. PublishView™ objects containing text,
hyperlinks, videos and images are not converted.
• You cannot create or open a PublishView™ document on a handheld. You must
convert a PublishView™ document to a TI-Nspire™ document before sending it to a
handheld.
Exploring a PublishView™ Document
The following example shows how you might use TI-Nspire™ applications and
PublishView™ objects to build a PublishView™ document. In this example, borders are
turned on to show the boundaries around the objects. Showing borders enables you to
work with objects easily while building a document. When you are ready to print or
publish the document to the web, you can select to the hide borders.
ÀHeader. In this example, the header contains the title of the document. When the
Working with PublishView™ Documents 68
69 Working with PublishView™ Documents
header area is active, you can type and format text as needed.
ÁProblem break and name. In PublishView™ documents, use problem breaks to
control the page layout. You can select to hide or show problem breaks. Deleting a
problem removes the contents of the problem and removes the space between
problems when there are multiple problems. Problem breaks also enable you to use
variables in PublishView™ documents. Variables that have the same name are
independent of one another if they are used in different problems.
ÂText boxes. In this example, the introduction text and the text in boxes 1, 2, 3 and 4
is contained in text boxes. You can insert text and hyperlinks into a PublishView™
document using a text box. Text boxes can be resized and positioned as needed.
PublishView™ text boxes are not retained when you convert a PublishView™
document to a TI-Nspire™ document.
ÃTI-Nspire™ applications. In this example, the author uses Graphs & Geometry to
show the maths functions. When a TI-Nspire™ application is active in a PublishView™
document, the appropriate application menu opens in the Documents Toolbox. You
can work in a TI-Nspire™ application just as you would in a TI-Nspire™ document.
When you convert a PublishView™ document to a TI-Nspire™ document, applications
are retained.
ÄNotes application. You can also use the TI-Nspire™ Notes application to add text to a
PublishView™ document. Because Notes is a TI-Nspire™ application, it will be
retained when you convert the PublishView™ document to a TI-Nspire™ document.
Using the Notes application enables you to use an equation editor and can contain
TI-Nspire™ maths templates and symbols.
ÅVideo. This is an example of a video that is embedded in a PublishView™ document
within a frame. Users can start and stop the video using the controls. Frames
containing videos and images can be resized and positioned in the document as
needed.
ÆFooter. By default, the footer area contains the page number, which cannot be
edited. You can add other text above the page number if needed. Like the header,
you can format text as needed.
Using the Status Bar in a PublishView™ Document
When a PublishView™ document is open, options on the status bar are different than
when working in a TI-Nspire™ document.
ÀDocument names are displayed in tabs. If multiple documents are open, the
document names are listed. You can have TI-Nspire™ and PublishView™ documents
open at the same time. In this example, Document 1 is an inactive TI-Nspire™
document ( ). Document 2 is the active PublishView™ document ( ). Click the X to
close a document.
ÁPage Size. Shows the document's page size as Handheld or Computer. You can use
the TI-Nspire™ File menu to convert a document from one page size to the other.

to an active document or set default settings for all PublishView™ documents. When
you convert a TI-Nspire™ document into a PublishView™ document, the settings in
the TI-Nspire™ document convert to the settings defined for PublishView™
documents.
ÃUse the Zoom scale to zoom the active document in or out from 10% to 500%. To set
a zoom, type a specific number, use the + and - buttons to increase or decrease by
increments of 10%, or use the drop-down box to choose pre-set percentages.
ÄIn TI-Nspire™ applications, use the Boldness scale to increase or decrease the
boldness of text and line thickness within applications. To set the boldness, type a
specific number, use the + and - buttons to increase or decrease by increments of
10%, or use the drop-down box to choose pre-set percentages.
For PublishView™ objects, boldness is used to match text within TI-Nspire™
applications to other text on the PublishView™ sheet. It can also be used to increase
the visibility of TI-Nspire™ applications when presenting a document to a class.
ÅWhen there are too many open document names to show in the status bar, click the
forward and backward arrows ( ) to move through the documents.

Using Context Menus
In TI-Nspire™ applications and in PublishView™ documents, context menus provide a
list of options specific to the task you are working on. For example, when you right-
click a cell while working in the TI-Nspire™ Lists & Spreadsheet application, a context
menu opens providing a list of actions that you can perform on that cell. When you
right-click the border of a text box in a PublishView™ document, the context menu
provides actions that can be performed on the text box.
Context Menus in TI-Nspire™ Applications
When you insert a TI-Nspire™ application into a PublishView™ document, the
application menu and the context menus associated with that application are available
and work the same way they work in a TI-Nspire™ document.
Context Menus in PublishView™ Documents
In PublishView™ documents, context menus provide shortcuts to frequently performed
tasks. Context menus are specific to an object or area:
• The Sheet context menu provides options for working with the layout of the sheet
and document.
• Object context menus provide options for manipulating the object.
• Content-sensitive context menus provide options for working with the content
inside the object such as text or a video.
Working with PublishView™ Objects
In a PublishView™ document, text, hyperlinks, images and videos are contained in
PublishView™ objects. You can move, resize, copy and paste and delete an object
within a PublishView™ document. Objects can also be positioned so that one overlaps
the other.
Within a document, PublishView™ objects can exist in three states: unselected,
selected and interactive.
State Description
Unselected When unselected, an object does
not have handles for
repositioning and sizing. To
deselect an object, left-click or
right-click outside the object.
In this example, borders around
the object are showing.
State Description
Selected When selected, an object will
have eight square handles
framing the object. To select an
object, click the object’s border.
When selected, objects can be
moved and resized.
• To move an object, click a
border and drag the object
to its new location.
• To resize an object, grab a
handle.
• Right-click the border to
open a context menu with
options for manipulating the
object.
Interactive An interactive state is indicated
by a blue frame around the
object. To enter interactive
state, left-click or right-click
anywhere in the body of the
object. When in an interactive
state, you can work with the
contents of the object. For
example, you can add or edit text
in a text box or complete maths
functions in a TI-Nspire™
application. When in an
interactive state, context menus
contain options specific to the
contents of an object.
Inserting an Object
1. In the Documents Toolbox, ensure the PublishView™ Objects menu is open.

each other on the PublishView™ sheet. Move the top page to see the other pages.
Working with Problems
Like a TI-Nspire™ document, a PublishView™ document consists of one or more
problems.
Problems are used to control the layout of a PublishView™ document so that you can
isolate variables. When variables with the same name are used in multiple problems,
variables can have different values. To add problems to PublishView™ documents,
open the Sheet context menu or use the options on the Insert menu in the Documents
Workspace. When adding problems, keep the following guidelines in mind:
• By default, a new PublishView™ document contains one problem.
• You can insert a problem after any existing problem.
• You cannot insert a problem in the middle of an existing problem.
• A new problem break is always inserted after the selected problem.
• Inserting a problem break adds empty space below the break.
• Any object between two problem breaks is part of the problem above the break.
Working with PublishView™ Documents 84
85 Working with PublishView™ Documents
• The last problem includes all sheets and objects below the last problem break.

Adding Text to a PublishView™ Document
In a PublishView™ document, there are three ways to add text:
• Insert a PublishView™ text box to enter free-form text or copy text from other
sources into the document. For example, you can place a PublishView™ text box
next to an image and type a description in a text box. You can also copy and paste
text from .doc, .txt and .rtf files. Use PublishView™ text boxes when you need
options for emphasizing and formatting text. PublishView™ text boxes are not
converted when you convert a PublishView™ document to a TI-Nspire™ document.
You may want to use a PublishView™ text box to add text that you don’t want
handheld users to see.
• Use the TI-Nspire™ Notes application. You should use the Notes application when
you need an advanced equation editor and when you need to use TI-Nspire™ maths
templates and symbols. Superscript and subscript are also easier to use in the
Notes application. You should also use Notes when you are planning to convert the
PublishView™ document to a TI-Nspire™ document for use on a handheld and you
want handheld users to see the text.
• Add text in TI-Nspire™ applications that allow text just as you would in a
TI-Nspire™ document.

Using Hyperlinks in PublishView™ Documents
In PublishView™ documents, use hyperlinks to:
• Link to a file
• Link to a website on the Internet
You can add a hyperlink to an open document or you can convert any text within a text
box to a hyperlink. When a hyperlink is added, the formatting of the text is underlined
and the font colour is blue. You can change the formatting of the hyperlinked text
without losing the hyperlink.
If a link is broken, an error message is displayed when you click the link:
• Cannot open the specified file
• Cannot open the specified web page
PublishView™ text boxes support both absolute and relative links.
Absolute links contain the complete location of the linked file and do not depend on the
location of the main document.
Relative links contain the location of the linked file relative to the main document. If
you have multiple lessons in a single folder and they are all linked using relative
addressing, you can move the folder to any other location (another local folder,
datashare, flash drive, online) without breaking the links. The links also stay intact if
you bundle the documents into a lesson bundle or zip them into a zip file and share
them.
Note: The PublishView™ document must be saved before you can insert a relative
hyperlink.
Linking to a File
You can link to any file on your computer. If the file type is associated with an
application on your computer, it will launch when you click the link. There are two ways

Understanding the File System
The TI-Nspire™ Student Software or TI-Nspire™ CAS Student Software sets up a file
system on the student’s computer when the software is installed. The student can
install the software anywhere, but once it is installed, the location cannot be changed.
The files are stored in the folder TI-Nspire\[Classname]. The system creates a new
class folder for each class.
The TI-Nspire™ Navigator™ NC Teacher Software automatically sends and collects files
to and from the current class folder on the student’s computer. Students are
responsible for keeping the files in this folder.
The teacher can send or collect any type of file.
Understanding File Transfers
During a class session, the teacher can send files to student computers and collect or
delete files from student computers.
Note: Before class starts, teachers can set up actions to send or collect files. When you
log in, the files are sent or collected. If the teacher set up actions to both send and
collect files, you will only see the dialogue box for the last action completed.

- If you do not check Accept equivalent responses as correct, the student
response is marked correct if it is an exact text match to one of the
accepted responses you entered.
- If you do check Accept equivalent responses as correct, the student
response is marked correct if it is equivalent to any accepted response you
entered. For example, if you typed x+2 as the correct answer, and the
student submits 2+x, this response is equivalent to the accepted response
and is automatically graded as correct. Spaces, case differences and extra
parentheses are ignored when the software evaluates student answers. For
example, y=2x+1 is evaluated the same as Y=2X+1.

boxes and accept only expression inputs such as 2(3+5).
7. Open the Configuration tool to set the response type as Number or Expression, set
whether or not the students should show their work and enter a correct answer.
You can also set a tolerance for Number types, or equivalent responses for
Expression types.
• The Show your work option includes areas for the students to write their
starting point, their steps and their final answer.
• In the Number type response, enter the accepted numerical response and the
tolerance. Student responses are marked correct if they fall within the
tolerance interval you specify.
• Specifying a tolerance of zero indicates you are looking for the exact number
answer. Not specifying a tolerance is the same as specifying a tolerance of
zero.
• Student answers are considered correct if they are numerically equivalent to
the correct answer. Spaces, case differences and extra parentheses are ignored
when the software evaluates student answers.
• In the Expression type response, you can add additional fields (up to 10) for
multiple correct answers.
• In the Expression type response, click to open the Templates and Symbols
catalogue that allows you to enter 2D maths expressions.
• In the Expression type response, you can select whether or not to accept
equivalent responses as correct.
- If you do not check Accept equivalent responses as correct, the student
response is marked correct if it is an exact text match to one of the
accepted responses you entered.
- If you do check Accept equivalent responses as correct, the student
response is marked correct if it is equivalent to any accepted response you
entered. For example, if you typed x+2 as the correct answer, and the
student submits 2+x, this response is equivalent to the accepted response
and is automatically graded as correct. Spaces, case differences and extra
parentheses are ignored when the software evaluates student answers. For
example, x+2 is evaluated the same as X+2.
Important: Students can enter the starting expression you supply and have
this response automatically graded as correct. For example, if you ask
students to factor x2-7x+12 and stipulate the correct answer is (x-3)(x-4),
the student can submit a response of x2-7x+12. This response is
automatically graded as correct because it is equivalent to the accepted
answer. You must manually mark this student response as incorrect in
either the Review or Portfolio Workspaces. See the chapters for those
workspaces for more information on marking and grading responses.

Response assignment contains a question that requires the word “Autumn” as the
correct answer. One student has entered “Fall.” If you want to give the student full or
partial credit, you can do so by changing the student’s score for the question.
In addition to editing an individual student score, you can edit the total possible points
for each question, the extra points, and the final percentage.
▶Use whole numbers to edit the scores. For example, type 75 to give a score of 75%,
type 100 to give a score of 100%, and so forth.
Note: If you type a score and do not press Enter, the change is not made, and the
previous score remains in place.
Previewing a Student’s Answer
You can preview a student’s answer to an individual assignment question in the
Preview Pane. This provides a quick, easy, and efficient method for the review of
questions, answers, and the modification of scores.
Note: The assignment must contain at least one question to be previewed.
1. Click an individual assignment in the Assignments Summary list.
2. Select the question cell you want to preview.
The following information is shown in the Preview Pane.
•Q#Question. Original question with icon showing correct or incorrect response
•Student’s Answer. Student’s response
•Correct Response. Teacher’s correct response (blank if there is no correct
response)
Note: Depending on the question posted, additional information may be displayed.
Modifying a Student’s Score for an Assignment
You can edit the score for an assignment from the Assignments Summary view, or you
can edit the score for individual questions in an assignment from the Individual
Assignments view. These steps describe how to change a score from either view.
1. In the student row, select the score you want to edit.
2. Right-click the cell and click Edit Score.

The software asks if you want to keep the student scores for the question, or
reassess the scores for each student. The default setting is to reassess the scores
for each student.
• To keep the student scores without making changes, select Leave student
assigned credit for this question intact.
• To reassess the score for each student, select Reassess question for each
student.
4. Click OK.
Changing the Final Percentage Score
1. In the Individual Assignments view, select the student whose score you want to
edit.
2. Right-click the cell in the Final column, and click Edit Score.

Working with Variables
When you first store a value in a variable, you give the variable a name.
• If the variable does not already exist, Calculator creates it.
• If the variable already exists, Calculator updates it.
Variables within a problem are shared by TI-Nspire™ maths and science learning
technology applications. For example, you can create a variable in Calculator and then
use or modify it in Graphs & Geometry or Lists & Spreadsheet within the same
problem.
For more information, see UsingVariables.
Creating User-defined Functions and Programmes
You can use the Define command to create your own functions and programmes. You
can create them in the Calculator application or in the Programme Editor and then use
them in other TI-Nspire™ applications.
For more information, see Overview of the Programme Editor and Libraries.
Defining a Single-line Function
Suppose you want to define a function named cube() that calculates the cube of a
number or variable.
1. On the Calculator entry line, type Define cube(x)=x^3 and press Enter.
Calculator Application 266
267 Calculator Application
The message “Done” confirms that the function has been defined.
2. Type cube(2) and press Enter to test the function.
Defining a Multiple-line Function Using Templates
You can define a function consisting of multiple statements entered on separate lines.
A multiple-line function may be easier to read than one with multiple statements
separated by colons.
Note: You can create multiple-line functions only by using the Define command. You
cannot use the := or →operators to create multiple-line definitions. The
Func...EndFunc template serves as a container for the statements.
As an example, define a function named g(x,y)that compares two arguments xand y.
If argument x> argument y, the function should return the value of x. Otherwise, it
should return the value of y.
1. On the Calculator entry line, type Define g(x,y)=. Do not press Enter yet.
2. Insert the Func...EndFunc template.
From the Functions&Programmes menu, select Func...EndFunc.
Calculator inserts the template.
3. Insert the If...Then...Else...EndIf template.
From the Functions&Programmes menu, select Control, and then select
If...Then...Else...EndIf.
Calculator inserts the template.
4. Type the remaining parts of the function, using the arrow keys to move the cursor
from line to line.
5. Press Enter to complete the definition.
6. Evaluate g(3,-7) to test the function.
Defining a Multiple-line Function Manually
Within a multi-line template such as Func...EndFunc or If...EndIf, you can start a new
line without completing the definition.
•Handheld: Press @instead of ·.
•Windows®: Hold Alt and press Enter.
•Macintosh®: Hold Option and press Enter.

Using Variables
A variable is a defined value that can be used multiple times in a problem. You can
define a value or function as a variable within each application. Within a problem,
variables are shared by TI-Nspire™applications. For example, you can create a variable
in Calculator, and then use or modify it in Graphs & Geometry or Lists & Spreadsheet
within the same problem.
Each variable has a name and a definition and the definition can be changed. When
you change the definition, all occurrences of the variable in the problem are updated to
use the new definition. In the TI-Nspire™ software, a variable has four attributes:
• Name - User-defined name assigned when the variable is created.
• Location - Variables are stored in memory.
• Value - Number, text, mathematical expression or function.
• Type - Type of data that can be stored as a variable.
Note: Variables created with the Local command within a user-defined function or
programme are not accessible outside that function or programme.
Linking Values on Pages
Values and functions created or defined in one application can interact with other
applications (within the same problem) to share data.
When using linked items, keep in mind:
• Values can be linked between applications on one page or between different pages
of the same problem.
• All applications are linked to the same data.
• If the linked value is changed in the original application, the change is reflected in
all linked usages.
Defining a variable is the first step in linking values.
Creating Variables
Any portion or attribute of an object or function created within an application can be
stored as a variable. Examples of attributes that can become variables are the area of
a rectangle, the radius of a circle, the value contained in a spreadsheet cell or the
contents of a row or column or a function expression. When you create a variable, it is
stored in memory.
Types of Variables
You can store the following data types as variables:
Using Variables 278
279 Using Variables
Data type Examples
Expression
2.541.25E62pxmin/102+3i(xN2)2

3. Press / h and then type the variable name num.
This means: Calculate 5+83and store the result as a variable named num.
4. Press ·.
Calculator creates the variable num and stores the result there.
Creating a Variable in the Computer Software
When creating a variable in the computer software, use the following conventions. As
alternatives to using &(store), you can use “:=” or the Define command. All of the
following statements are equivalent.
5+83&num
num := 5+83
Define num=5+83
Checking a Variable’s Value
You can check the value of an existing variable by entering its name on the Calculator
entry line. When you type the name of a stored variable, it appears in bold type.
▶On the Calculator entry line, type the variable name num and press ·.
The value most recently stored in num is displayed as the result.
Automatically Creating Variables in Graphs & Geometry
In the Graphs and Geometry applications, functions defined on the entry line are
automatically stored as variables.
In this example, f1(x)=x3is a variable definition, which allows it to be displayed in
other applications including a table in the Lists & Spreadsheet application.

horizontal and vertical axes. Click the number for an end value to highlight it in the
entry field. Name the variable and store it for use with other applications by using any
method described in Step 2.
Automatically Creating Variables in Lists & Spreadsheet
Naming a list at the top of a Lists & Spreadsheet column automatically stores that
value as a list variable. This variable can be used in other applications including Data &
Statistics.
Creating a Variable from a Lists & Spreadsheet Cell Value
You can share a cell value with other applications. When defining or referring to a
shared cell in Lists & Spreadsheet, precede the name with an apostrophe (‘).
1. Click the cell that you want to share.
2. Click to open the Variables menu.

problem.
Note: If a variable with the name you specified already exists in the current problem
space, Lists & Spreadsheet displays an error message.
Using (Linking) Variables
Sharing, or linking, the variables you create is a powerful tool for maths exploration.
The display of linked variables is automatically updated when the variable’s value
changes.
Linking to Shared Variables
To use a stored variable:
1. Display the page and select the location or object to which you want to link a
variable.
2. Select the Variables tool h.
The Variables options are displayed. The software knows which types of variables
will work in the location or with the object selected and will only display those
variables.
3. Use 9and :to scroll the list.
—or—
Type part of the variable name.
As you type, the system displays a list of variables that begin with the letters you

list is long.
4. When you locate and highlight the name of the variable you want to use, click the
name.
—or—
Press ·.
The selected variable value is linked.
Linking a Lists & Spreadsheet Cell to a Variable
When you link a cell to a variable, Lists & Spreadsheet keeps the cell value updated to
reflect the current value of the variable. The variable can be any variable in the current
problem and can be defined in Graphs & Geometry, Calculator or any instance of Lists
& Spreadsheet.
Note: Do not link to a system variable. Doing so could prevent the variable from being
updated by the system. System variables include ans,StatMatrix and statistics results
(such as RegEqn,dfError and Resid).
1. Click the cell that you want to link to the variable.
2. Open the VarLink menu:
- Click , and then click Cell.
- Handheld: Press h.
The VarLink menu is displayed.

substitute for the stored value.
1. Enter the expression:
- Type 4*25*num^2 on the entry line and press Enter.
- Handheld: Type 4r25 rnum^2 on the entry line and press ·.
Calculator substitutes 517, the value currently assigned to num and evaluates the
expression.
2. Enter the expression:
- Type 4*25*nonum^2 and press Enter.
- Handheld: Type 4r25 rnonum^2 on the entry line and press ·.
CAS: Because the variable nonum has not been defined, it is treated algebraically in
the result.
Because the variable nonum has not been defined, the expression returns an error
message.
Using Variables 284
285 Using Variables
Naming Variables
Variable and function names that you create must meet the following naming rules.
Note: In the unlikely event that you create a variable with the same name as one used
for statistical analysis or by the Finance Solver, an error condition could occur. If you
begin entering a variable name that is already in use in the current problem, the
software shows the entry in bold to let you know.
• Variable names must be in one of the forms xxx or xxx.yyy. The xxx part can have
1 to 16 characters. The yyy part, if used, can have 1 to 15 characters. If you use the
xxx.yyy form, both xxx and yyy are required; you cannot start or end a variable
name with a period “.”.
• Characters can consist of letters, digits and the underscore character (_). Letters
can be U.S. or Greek letters (but not Πor p), accented letters and international
letters.
• Do not use cor nfrom the symbol palette to construct a variable name such as c1
or n12. These may appear to be letters, but they are treated internally as special
symbols.
• You can use uppercase or lowercase letters. The names AB22,Ab22,aB22 and
ab22 all refer to the same variable.
• You cannot use a digit as the first character of xxx or yyy.
• You can use digits 0 through 9, U.S. letters, a - z, Latin and Greek letters (but not p)
as subscripts (for example, a2,qa, or h2o). To enter a subscript while typing a
variable name, select in the Math Templates or on the formatting toolbar.
• Do not use spaces.
• If you want a variable to be treated as a complex number, use an underscore as the
last character of the name.
• CAS: If you want a variable to be treated as a type of unit (such as _m or _ft), use
an underscore as the first character of the name. You cannot use subsequent
underscores in the name.
• You cannot use an underscore as the first character of the name.
• You cannot use a preassigned variable, function or command name, such as Ans,
min or tan.
Note: For more information about TI-Nspire™ functions, see the Reference Guide.
• Library documents and library objects are subject to additional naming restrictions.
For more information, see Libraries.
Here are some examples:
Variable names Valid?
Myvar, my.var Yes
Variable names Valid?
My var, list 1 No. Contains a space.
a, b, b12, b12, c, d Yes. Note that variables b12 and b12 are distinct.
Log, Ans No. Preassigned to a system function or variable.
Log1, list1.a, list1.b Yes
3rdTotal, list1.1 No. xxx or yyy starts with a digit.
Adjusting Variable Values with a Slider
A slider control lets you interactively adjust or animate the value of a numeric variable.
You can insert sliders in the Graphs, Geometry, Notes and Data&Statistics
applications.
Horizontal slider for adjusting variable v1.
Minimised vertical slider for adjusting variable v2.

unintended changes to a variable.
Using Variables 288
289 Using Variables
Time and altitude lists can be locked to ensure
problem fidelity
Reference function f1 can be locked to prevent
unintended change
Variables you Cannot Lock
• System variable Ans
•stat. and tvm. variable groups
Important Information About Locked Variables
• To lock variables, use the Lock command.
• To modify or delete a locked variable, you must first unlock the item.
• Locked variables display a lock icon on the variable menu list.
• The Lock command clears the Redo/Undo history when applied to unlocked
variables.
Examples of Locking
Lock a,b,c Locks variables a,band cfrom the Calculator application.

Reusing the Last Answer
Each instance of Calculator automatically stores the last calculated result as a variable
named Ans. You can use Ans to create a chain of calculations.
Note: Do not link to Ans or any system variable. Doing so could prevent the variable
from being updated by the system. System variables include statistics results (such as
Stat.RegEqn,Stat.dfError and Stat.Resid) and Finance Solver variables (such as
tvm.n,tvm.pmt and tvm.fv).
As an example of using Ans, calculate the area of a garden plot that is 1.7 meters by
4.2 meters. Then use the area to calculate the yield per square meter if the plot
produces a total of 147 tomatoes.

Introduction to Geometric Objects
Geometry tools are accessible in both the Graphs and Geometry applications. You can
use these tools to draw and investigate objects such as points, lines, and shapes.
• The Graphing view shows the Graphs work area superimposed on the Geometry
work area. You can select, measure, and alter objects in both work areas.
• The Plane Geometry view shows only the objects created in the Geometry
application.
Objects Created in the Graphs Application
Points, lines, and shapes created in the Graphs application are analytic objects.
• All points that define these objects reside on the x,y graph plane. Objects created
here are visible only in the Graphs application. Changing the axes scale affects the
appearance of the objects.
• You can display and edit the coordinates of any point on an object.
• You can display the equation of a line, tangent line, circle shape, or geometric conic
created in the Graphs application.
The circle arc and polygon were created in the Geometry application. The sine wave and conic
were created in the Graphs application.
Objects Created in the Geometry Application
Points, lines, and shapes created in the Geometry application are not analytic objects.
• Points that define these objects do not reside on the graph plane. Objects created
here are visible in both the Graphs and Geometry applications, but they are
unaffected by changes to the Graphs x,y axes.
• You cannot obtain the coordinates of an object’s points.
• You cannot display the equation of a geometric object created in the Geometry
application

Creating Shapes Using Gestures (MathDraw)
The MathDraw tool lets you use touchscreen or mouse gestures to create points, lines,
circles and other shapes.
MathDraw is available in:
• Geometry view without the analytic window displayed.
• Graphing view when the x scale and y scale are identical. This avoids non-circular
ellipses and non-square rectangles appearing as circles and squares.
MathDraw is not available in the 3D Graphing view or in the Geometry view with the
analytic window displayed.
Activating MathDraw
1. If using the Geometry view with the analytic window visible, use the View menu to
hide the window.
2. On the Actions menu, select MathDraw.
The MathDraw icon appears. You can begin using the tool.
Cancelling MathDraw
▶When you have finished using the MathDraw tool, press Esc.
The tool also closes if you select a different tool or change views.
Creating Points
To create a labelled point, tap or click in an open area.
• If the point is close to an existing line, segment, ray, geometric conic (including
circles) or polygon, the point snaps to that object. You can also place a point on the
intersection of any two of those types of objects.
• If the point is close to a visible grid location in a Graphs view or the analytic
window of a Geometry view, it snaps to the grid.
Drawing Lines and Segments
To create a line or segment, touch or click the initial position, and then drag to the end
position.
• If the drawn line passes near an existing point, the line snaps to the point.
• If the drawn line starts close to an existing point and ends next to another existing
point , it becomes a segment defined by those points.
• If the drawn line is nearly parallel or perpendicular to an existing line, segment or
side of a polygon, it aligns to that object.
Note: The default tolerance for detecting parallel/perpendicular lines is 12.5
degrees. This tolerance can be redefined using a variable named
ti_gg_fd.angle_tol. You can change the tolerance in the current problem by setting
this variable in the calculator app to a value in the range 0 through 45 (0=no
parallel/perpendicular detection).
Drawing Circles and Ellipses
To create a circle or ellipse, use the touchscreen or mouse to draw the approximate
shape.
• If the drawn shape is sufficiently circular, a circle is created.
• If the shape is elongated, an ellipse is created.
• If the virtual centre of the drawn shape is near an existing point, the circle or
ellipse is centred on that point.
Drawing Triangles
To create a triangle, draw a triangle-like shape.
• If a drawn vertex is close to an existing point, the vertex snaps to the point.
Drawing Rectangles and Squares
To create a rectangle or square, use the touchscreen or mouse to draw the perimeter.
• If the drawn shape is nearly square, a square is created.
• If the drawn shape is elongated, a rectangle is created.
Geometry Application 308
309 Geometry Application
• If the centre of a square is close to an existing point, the square snaps to that
point.
Drawing Polygons
To create a polygon, tap or click a succession of existing points, ending on the first
point you tapped.
Using MathDraw to Create Equations
In the Graphs view, MathDraw attempts to recognise certain gestures as functions for
analytic parabolas.
Note: The default step value for quantisation of the parabola coefficients is 1/32. The
denominator of this fraction can be redefined using a variable named ti_gg_fd.par_
quant. You can change the step value in the current problem by setting this variable to
a value greater or equal to 2. A value of 2, for example, produces a step value of 0.5.
Using MathDraw to Measure an Angle
To measure the angle between two existing lines, use the touchscreen or mouse to
draw a circle arc from one of the lines to the other.
• If the intersection point between the two lines does not exist, it is created and
labelled.
• The angle is not a directed angle.
Using MathDraw to Find a Mid-point
To create a point midway between two points, tap or click point1, point2, and then
point1 again.
Using MathDraw to Erase
To erase objects, use the touchscreen or mouse to drag left and right, similar to the
motion of erasing a whiteboard.
• The erasure area is the bounding rectangle of the erasure gesture.
• All point objects and their dependents inside the erasure area are removed.

Working with Shaded Areas
As you change the bounds or redefine the curves, the shading and the area value are
updated.
• To change the lower or upper bound, drag it or type new coordinates for it. You
cannot move a bound that resides on an intersection. However, the point moves
automatically as you edit or manipulate the curves.
• To redefine a curve, either manipulate it by dragging or edit its expression in the
entry line.
If an endpoint resided originally on an intersection, and the redefined functions no
longer intersect, the shading and area value disappear. If you redefine the function
(s) so that there is an intersection point, the shading and area value reappear.
• To delete or hide the shaded area, or to change its colour and other attributes,
display its context menu.

Introduction to Geometric Objects
Geometry tools are accessible in both the Graphs and Geometry applications. You can
use these tools to draw and investigate objects such as points, lines, and shapes.
• The Graphing view shows the Graphs work area superimposed on the Geometry
work area. You can select, measure, and alter objects in both work areas.
• The Plane Geometry view shows only the objects created in the Geometry
application.
Objects Created in the Graphs Application
Points, lines, and shapes created in the Graphs application are analytic objects.
• All points that define these objects reside on the x,y graph plane. Objects created
here are visible only in the Graphs application. Changing the axes scale affects the
appearance of the objects.
• You can display and edit the coordinates of any point on an object.
• You can display the equation of a line, tangent line, circle shape, or geometric conic
created in the Graphs application.
The circle arc and polygon were created in the Geometry application. The sine wave and conic
were created in the Graphs application.
Objects Created in the Geometry Application
Points, lines, and shapes created in the Geometry application are not analytic objects.
• Points that define these objects do not reside on the graph plane. Objects created
here are visible in both the Graphs and Geometry applications, but they are
unaffected by changes to the Graphs x,y axes.
• You cannot obtain the coordinates of an object’s points.
• You cannot display the equation of a geometric object created in the Geometry
application

Creating Shapes Using Gestures (MathDraw)
The MathDraw tool lets you use touchscreen or mouse gestures to create points, lines,
circles and other shapes.
MathDraw is available in:
• Geometry view without the analytic window displayed.
• Graphing view when the x scale and y scale are identical. This avoids non-circular
ellipses and non-square rectangles appearing as circles and squares.
MathDraw is not available in the 3D Graphing view or in the Geometry view with the
analytic window displayed.
Activating MathDraw
1. If using the Geometry view with the analytic window visible, use the View menu to
hide the window.
2. On the Actions menu, select MathDraw.
The MathDraw icon appears. You can begin using the tool.
Cancelling MathDraw
▶When you have finished using the MathDraw tool, press Esc.
The tool also closes if you select a different tool or change views.
Creating Points
To create a labelled point, tap or click in an open area.
• If the point is close to an existing line, segment, ray, geometric conic (including
circles) or polygon, the point snaps to that object. You can also place a point on the
intersection of any two of those types of objects.
• If the point is close to a visible grid location in a Graphs view or the analytic
window of a Geometry view, it snaps to the grid.
Drawing Lines and Segments
To create a line or segment, touch or click the initial position, and then drag to the end
position.
• If the drawn line passes near an existing point, the line snaps to the point.
• If the drawn line starts close to an existing point and ends next to another existing
point , it becomes a segment defined by those points.
• If the drawn line is nearly parallel or perpendicular to an existing line, segment or
side of a polygon, it aligns to that object.
Note: The default tolerance for detecting parallel/perpendicular lines is 12.5
degrees. This tolerance can be redefined using a variable named
ti_gg_fd.angle_tol. You can change the tolerance in the current problem by setting
this variable in the calculator app to a value in the range 0 through 45 (0=no
parallel/perpendicular detection).
Drawing Circles and Ellipses
To create a circle or ellipse, use the touchscreen or mouse to draw the approximate
shape.
• If the drawn shape is sufficiently circular, a circle is created.
• If the shape is elongated, an ellipse is created.
• If the virtual centre of the drawn shape is near an existing point, the circle or
ellipse is centred on that point.
Drawing Triangles
To create a triangle, draw a triangle-like shape.
• If a drawn vertex is close to an existing point, the vertex snaps to the point.
Drawing Rectangles and Squares
To create a rectangle or square, use the touchscreen or mouse to draw the perimeter.
• If the drawn shape is nearly square, a square is created.
• If the drawn shape is elongated, a rectangle is created.
Graphs Application 390
391 Graphs Application
• If the centre of a square is close to an existing point, the square snaps to that
point.
Drawing Polygons
To create a polygon, tap or click a succession of existing points, ending on the first
point you tapped.
Using MathDraw to Create Equations
In the Graphs view, MathDraw attempts to recognise certain gestures as functions for
analytic parabolas.
Note: The default step value for quantisation of the parabola coefficients is 1/32. The
denominator of this fraction can be redefined using a variable named ti_gg_fd.par_
quant. You can change the step value in the current problem by setting this variable to
a value greater or equal to 2. A value of 2, for example, produces a step value of 0.5.
Using MathDraw to Measure an Angle
To measure the angle between two existing lines, use the touchscreen or mouse to
draw a circle arc from one of the lines to the other.
• If the intersection point between the two lines does not exist, it is created and
labelled.
• The angle is not a directed angle.
Using MathDraw to Find a Mid-point
To create a point midway between two points, tap or click point1, point2, and then
point1 again.
Using MathDraw to Erase
To erase objects, use the touchscreen or mouse to drag left and right, similar to the
motion of erasing a whiteboard.
• The erasure area is the bounding rectangle of the erasure gesture.
• All point objects and their dependents inside the erasure area are removed.

defining a list, you can link to it from the Graphs&Geometry, Calculator or
Data&Statistics applications, and from other instances of the Lists&Spreadsheet
application within the current problem.
Note: Lists&Spreadsheet can display a maximum of 2500 elements in a list.
Sharing a Spreadsheet Column as a List Variable
You share a column of data by naming it as a list variable.
Note: Avoid defining variables that use the same names as those used for statistical
analysis. In some cases, an error condition could occur.
Variable names used for statistical analysis are listed in the TI-Nspire™ Reference

1. Click the cell to move to the column’s name cell (the top cell of the column).
—or—
Press ▲as necessary.
2. Type a name for the list variable, and press Enter.
The column is now available as a list variable to other TI-Nspire™ applications.
3. Create elements in the list the same as you would create data in spreadsheet cells.
For example, you can type the data into each cell or use a formula to generate a
column of data.
Notes:
• If a variable with the name you specified already exists in the current problem,
Lists&Spreadsheet displays an error message.
• When you select the column formula cell of a list, it displays the list name in an
expression similar to width:=.
• Lists can contain empty elements (denoted by “_”) .
• You can refer to a specific element in a named list from the Calculator application.
Use the list name and the element’s position within the list. In a list named
Heights, for example, refer to the first element as Heights[1]. The expression
Heights[2] refers to the second element, and so on.
Linking to an Existing List Variable
Linking a column to an existing list variable lets you easily view and edit the values in
the list. The list can be any shared list in the current problem and can be defined in
Graphs&Geometry, Calculator or any instance of Lists&Spreadsheet.
After you link a column to a list, Lists&Spreadsheet automatically shows any changes
that you make to the list with other TI-Nspire™ applications.

(_). The underscore is automatically added to empty cells when a list is named or
when an empty cell is referenced in a formula. When you plan to perform
calculations on a range of cells, be sure to notice the location of void cells. Cells
without a value can affect calculations. For example, if you include a void cell in
the range for a sum such as “=b2+c2,” the result of the calculation is void(_).
Inserting a Cell Range into a Formula
The Select Range feature lets you insert a cell range (such as a1:b3) into a formula by
selecting the range instead of typing cell addresses into an argument.
Suppose you want to calculate the mean of a range of cells.
1. Select the cell that will contain the result.
2. From the Data menu, click ListMaths>Mean.
An editable formula appears in the cell.
Lists&Spreadsheet Application 430

calculate the mean.
Handheld: Move to the first cell in the range, hold g, and press the arrow keys.
The formula is updated as you select the cells.
5. Press Enter to complete the formula and display the result.
Navigating in a Spreadsheet
A spreadsheet includes a column letter at the top of each column and a row number on
the left of each row. The top two rows and the row numbers remain in place as you
scroll. You can name a column of data to make it available as a list variable in
TI-Nspire™ applications.
ÀColumn reference letter
ÁColumn name cell for defining a column as a list variable
ÂColumn formula cell for generating a column of data
ÃRow reference number
ÄBody Cells - Any empty (void) element in a list is displayed as an underscore (“_”).
Any value that cannot fit in a cell’s width is truncated (143489...). Hover over the
cell to display the complete value.

Working with Cells
Working with Colour
The Lists&Spreadsheet application displays black text and cells with a white
background by default. You can change the colour of cells and text to emphasize or
distinguish data. The colours and the order in which colour is assigned is based on the
TI-Nspire™ colour palette.
Changing the Fill Colour of Cells
1. Select the cells to fill with colour. You can choose one or more cells in any adjacent
cells, columns or rows.
2. Access the context menu and click Colour > Fill Colour.
3. Click the colour to apply to the cells.
Note: If you combine colour text and colour cells, choose colours carefully to ensure
visibility as you work with documents in the software and on the handheld.
Changing the Colour of Text
1. Select the cells that contain the text to change. You can choose one or more cells in
any adjacent cells, columns or rows.
2. Access the context menu and click Colour > Text Colour.
3. Click the colour to apply to the text. Empty cells in the selection area show the
colour change when text is added.
Understanding Cell References in Formulas
Use a cell reference to use data from a cell or range of cells in a formula. The
calculation results update automatically when values in cells change.
Relative references include only the cell’s column letter and row number (for example,
E7). A relative reference describes where a cell is in relation to other cells of the
spreadsheet. The Lists&Spreadsheet application keeps track of relative cell references
and adjusts the reference automatically when surrounding cells shift (because of
actions you perform, such as column deletions or cell insertions).
Follow these guidelines to specify cell references:
• Include a column letter and row number in a relative reference.
• Include the $symbol before both the column letter and the row number to specify
an absolute reference.
• Include a colon (:) between a two cell reference to specify a range of cells.
Absolute references include the $symbol before the column letter and before the row
number (for example, $B$16). Absolute references always refer to the cell in a specific
position in the spreadsheet. The application does not automatically adjust the cell
reference when cell positions change.
Typing a Cell Reference in a Formula
1. Double-click the cell and type the formula. For more information, see the
Calculator section.
2. Move to the appropriate position in the formula and type the cell reference. Use
the format for a relative reference (B3), absolute reference ($B$2) or range of cells
(A1:A4).
Note: You can click Recalculate on the Actions menu to update all references and
formula results in a spreadsheet.
Deleting the Contents of Cells
1. Click a cell to select it.
—or—
Use the arrow keys to move to the cell.
Note: If you are deleting a range of cells, select a cell at one end or corner of the
range, and then use Shift with the arrow keys to select the remaining cells in the
range.
2. Press Del.
Lists&Spreadsheet Application 434
435 Lists&Spreadsheet Application
Note: Any cell that uses a formula with an absolute reference to deleted data
shows an error. A cell that uses a formula with a relative reference to deleted data
is updated to use the data currently in the referenced position.
Copying Cells
When you copy cells, any formulas in the original cells are copied to the destination
cells.
1. Click the cell to copy.
—or—
Use the arrow keys to move to the cell.
Note: If you are copying a range of cells, select a cell at one end or corner of the
range, and then use Shift with the arrow keys to select the remaining cells in the
range.
2. Use the standard key short-cut for copying a selection.
Windows®: Press Ctrl+C.
Mac®: Press “+C.
Handheld: Press / C.
3. Click the cell where you want to duplicate the copied cell. If you are copying a block
of data, click the cell that will become the upper left corner of the copied block.
4. Paste the selected cells:
Windows®: Press Ctrl+V.
Mac®: Press “+V.
Handheld: Press / V.
Important: Paste copied data into a cell that is in the same mode as the cell from
which the data was originally copied. Otherwise, a formula could paste as a string
enclosed in quotes instead of a formula.
Filling Adjacent Cells
You can repeat a cell’s formula or value throughout adjacent cells within the row or
column. You can also repeat a range of cells horizontally or vertically. If you fill from a
range that contains a simple sequence (such as 2, 4, 6), the sequence continues in the
filled cells.
1. Click the cell that contains the value or formula to repeat.
Note: If you are repeating a range of cells, drag to select the range, or select a cell
at one end of the range, and then use Shift with the arrow keys to select the
remaining cells.
2. Click Data > Fill.
3. Use the arrow keys, or drag to select the range that will hold the repetitions.
4. Press Enter.
The value, formula or pattern that you selected for duplication is repeated over the
selected range.
Sharing a Cell Value as a Variable
You can share the value of a cell with other TI-Nspire™ applications by storing it as a
variable. When you define or refer to a shared cell or variable in Lists&Spreadsheet,
the name is preceded with an apostrophe(‘).
1. Click the cell that you want to share.
2. Click on the toolbar, and click Store Var to store the cell’s value.

Clearing Column Data
The Clear Data command lets you remove the data from selected columns. Clear Data
does not delete the column, and it does not clear a column’s name or formula.
After clearing the data, Lists&Spreadsheet recalculates column formulas for the
selected columns. This makes Clear Data useful for capturing a fresh set of data from
another application or selectively generating a fresh column of random numbers.
1. Click the column or columns that you want to clear.
2. From the Data menu, select Clear Data.
Note: If a recalculated formula produces the same data as before, it may appear
that the Clear Data command has failed.
Sorting Data
You can sort a selected area of the spreadsheet in ascending or descending order. You
select which column in the selected area will be used as the key for the sort. When the
sort moves data up or down in the key column, the corresponding data in the other
selected columns is also moved up or down. This preserves the integrity of each row.
Note: Sorting is based on numeric values. If you select a key column that contains text,
you could get unexpected results.
1. Select the range of cells.
2. From the Actions menu, select Sort.
The Sort dialogue box opens.
3. Click the column letter to use for ordering.
4. Click Descending or Ascending as the sort method, and then click OK.
Lists&Spreadsheet Application 440
441 Lists&Spreadsheet Application
Note: Sorting a column that is defined by a formula will remove the formula, because
it may not be valid after the sort.
Generating Columns of Data
You can create a column of values based on the contents of another column. You can
also create a column based on any of several types of sequential data.
Entering a formula in a column’s formula cell tells the Lists&Spreadsheet application
that you want to apply the formula to all cells in the column, not just to a single cell.
ÀColumn formula based on a variable
ÁColumn formula based on another column (column A)
ÂColumn formula that generates a sequence
Notes:
• If you generate data in a column that already contains one or more cell values,
Lists&Spreadsheet asks for confirmation before replacing the existing values.
Proceeding removes all of the existing values in the column.
• If you edit a cell manually in a column of generated data, Lists&Spreadsheet asks
for confirmation before replacing the generated data. Proceeding removes the
generated data for the entire column.
Creating Column Values Based on Another Column
1. Click the column formula cell (the second cell from the top) of the column where
you want to use a formula.
Lists&Spreadsheet inserts the leading equal sign (=) for the formula. If the
column is a named list, Lists&Spreadsheet inserts listname:= followed by the
cursor.
2. Type the expression for the formula after the = and press Enter Use brackets ([])
after any column letter you include in the formula. For example, type =a[]^2 to
create a column of values in which each cell is the square of the corresponding cell
of column A.
Lists&Spreadsheet shows the formula in the formula cell and fills the column
with the results.
Generating a Column of Random Numbers
This example generates a column of 20 random integers in the range 1 to 6.
1. Click the column formula cell (the second cell from the top) of the column.
Lists&Spreadsheet inserts the leading equal sign (=) for the formula. If the
column is a named list, Lists&Spreadsheet inserts listname:= followed by the
cursor.
2. After the equal sign, type RandInt(1,6,20).
Lists&Spreadsheet Application 442
443 Lists&Spreadsheet Application

3. Type the Formula that will be applied to the column values.
4. Type any Initial Terms required by the sequence. Separate them with commas.
5. Type a starting value for the independent variable (n0).
6. Type a maximum number of values to be generated (nMax).
7. Type the step value (nStep).
8. (Optional) Type a maximum value for the sequence in the Ceiling Value field.
9. Click OK.
Lists&Spreadsheet shows the formula in the formula cell and fills the column
with the results.
Graphing Spreadsheet Data
You can graph the data in a spreadsheet using Quick Graph or Summary Plot.
Lists&Spreadsheet cells that contain no data are not represented by data points on
graphs.
Using Quick Graph
You can easily create a dot plot of the data in one column or a scatter plot of two
adjacent columns by using the Quick Graph feature. This feature displays the graphed
data using the Data&Statistics application.
To create a scatter plot:
1. Name both of the columns to declare them as lists.
Lists&Spreadsheet Application 444
445 Lists&Spreadsheet Application
2. Select both columns.
3. From the Data menu, select Quick Graph.
A Data&Statistics application is added to the page with the plotted data. The
leftmost of the two lists is plotted on the x axis, and the other list is plotted on the
y axis.
4. (Optional) Use the Data&Statistics features to analyse or visually enhance the
graph.
Note: For more information, see Using Data and Statistics.
Creating a Summary Plot from a Summary Table
In this example, you create a summary table from raw data, and then use the table to
generate a summary plot. For more information, see Using Data&Statistics.
raw data summary table for eye colour based on raw data
A summary table contains an X (or Y) List and a Summary List.
• The X (or Y) List contains numeric or string values (such as 1999 or “colour”).
Numeric values result in a histogram. String values identify the categories for a bar
chart.
• The Summary List contains numeric values (such as count, frequency, or
probability) for each element in the other list.
To Create a Summary Plot:
Note: For situations in which you already have a summary table, you can skip the first
two steps.
Lists&Spreadsheet Application 446
447 Lists&Spreadsheet Application
1. Create a list that holds the category identifiers. For this example, name the list
“colour” and type strings for eye colour. Enclose category names in quotes to
prevent them from being interpreted as variables.
2. Create the summary list. For this example, name the list “counts” and type the
total count for each of the eye colours.
3. Select either list by clicking the top cell of the column and pressing▲.
4. From the Data menu, select Summary Plot.
The Summary Plot dialogue box opens.
5. If necessary, use Tab and the arrow keys to select the correct lists for X List and
Summary List.
6. In the Display On field, select how to display the summary plot in the
Data&Statistics application.
• Select Split Page to place the chart on half of the current page.
• Select New Page to add the chart on a new page.
The summary plot is displayed with the list names along the axes and a summary
plot symbol in the lower left corner of the chart window.
Note: In this example, the XList contains string data, so the summary plot displays
as a bar chart. The category strings from the list display beneath the bars.
Exchanging Data with Other Computer Software
You can use the TI-Nspire™ desktop software to copy table data to and from software
outside the TI-Nspire™ applications, such as TIDataEditor (in the TIConnect™
software) and Excel® spreadsheet software.
For example, you can copy:
• The values of individual cells, a range of cells or an entire list from TIDataEditor.
• The values (not the underlying formulas) of individual cells, a range of cells or an
entire column from an Excel® spreadsheet.
• A number from TIDataEditor.
• The value of a matrix from TIDataEditor.
Example - Copying Data from TIDataEditor
1. Open the TIConnect™ software.
2. Display the TIDataEditor.
3. If necessary, open the file containing the number, list or matrix that you want to

Capturing Data Automatically
When you capture data automatically, you can specify that you want the captures to be
triggered by:
• Changes in the captured variable only.
• Changes in the captured variable or additional variables.
This lets you set up multiple columns of synchronised captures, such as the x and y
coordinates of a moving object.
1. Clear all columns that you will be using for the captured data.
2. Make sure any data values that you want to capture are linked to variable names.
3. Click the column formula cell (the second cell from the top) of the column in which
you want to capture the values.
4. Click Data >Data Capture >Automatic.
A capture expression is inserted into the column formula cell with var as a
placeholder for the name of the variable you are capturing.
5. Replace the letters “var” with the name of the variable to capture. For example,

Variables menu.
The formula cell now contains an expression similar to =capture
(objpathX,1).
Lists&Spreadsheet Application 452
453 Lists&Spreadsheet Application
Note: The argument “1” tells Lists&Spreadsheet that you want the captures to be
triggered by the variable change.
6. If you want the capture to also be triggered by changes in an additional variable or
variables, type a comma after the 1, and then type the variable name or the name
of a list that itemises the variables.
The formula cell will contain an expression similar to =capture
(objpathX,1,objpathY).
7. Press Enter to complete the formula.
8. If you are capturing multiple columns of synchronised data, set up the additional
columns. For example, you might set up a second capture variable using
=capture(objpathY,1,objpathX).
9. When you are ready to capture the values, begin moving the object or start the
animation that affects it in Graphs&Geometry.
Each captured value is added to the end of the list.
Using Table Data for Statistical Analysis
Tools on the Statistics menu provide access to wizards that help you perform statistical
analyses on the data in table columns. You specify the location of the data, and
Lists&Spreadsheet stores the results in two columns: one for the result names, and
one for the corresponding values.
Plotting Statistical Data
Some statistics wizards include a Draw box. By default, the box is not selected.
Selecting this box creates a Data&Statistics work area on the page, displays the
calculated results in Lists&Spreadsheet, and draws the results of the statistical
analysis in the Data&Statistics work area.
Note: For functions that support the Draw option, the option is available only if you
type the function in a column formula cell.

Note: The results are linked to the source data. For example, if you change a value
in column A, the regression equation is updated automatically.
Storing Statistical Results
Lists&Spreadsheet stores statistical results using a variable-group name with the
format stat.nnn, where nnn is the result name (for example, stat.RegEqn and
stat.Resid). The use of standard names for variables makes it easier to identify and use
the statistical variables later. If you want to use a custom variable group instead of the
standard name, you can edit the formula in the column formula cell.
You could use the following formula to store the results in the variable group MystatsB.
=LinRegMx(a[],b[],1 ): CopyVar Stat., MystatsB.
Later, you could view the results by entering the following expression inthe Calculator
application or in another column of the Lists&Spreadsheet application:
MystatsB.results

Confidence Intervals
Supported Confidence Intervals
The following confidence intervals are available from the Lists&Spreadsheets
application. For more information regarding these functions, see the TI-Nspire™
Reference Guide.
z Interval (zInterval)
Computes a confidence interval for an unknown population mean, m, when the
population standard deviation, s, is known. The computed confidence interval depends
on the user-specified confidence level.
This test is useful in determining how far from a population mean a sample mean can
get before indicating a significant deviation.
t Interval (tInterval)
Computes a confidence interval for an unknown population mean, m, when the
population standard deviation, s, is unknown. The computed confidence interval
depends on the user-specified confidence level.
This test is useful in examining whether the confidence interval associated with a
confidence level contains the value assumed in the hypothesis. Like the z Interval, this
test helps you determine how far from a population mean a sample mean can get
before indicating a significant deviation when the population mean is unknown.
Lists&Spreadsheet Application 466
467 Lists&Spreadsheet Application
2-Sample z Interval (zInterval_2Samp)
Computes a confidence interval for the difference between two population means
(m1Nm2) when both population standard deviations (s1and s2) are known. The
computed confidence interval depends on the user-specified confidence level.
This test is useful in determining if there is statistical significance between the means
of two samples from the same population. For example, this test could determine
whether there is significance between the mean college entrance test score of female
students and the mean of college entrance test score of male students at the same
school.
2-Sample t Interval (tInterval_2Samp)
Computes a confidence interval for the difference between two population means
(m1Nm2) when both population standard deviations (s1and s2) are unknown. The
computed confidence interval depends on the user-specified confidence level.
This test is useful in determining if there is statistical significance between the means
of two samples from the same population. It is used instead of the 2-sample z
confidence interval in situations where the population is too large to measure to
determine the standard deviation.
1-Prop z Interval (zInterval_1Prop)
Computes a confidence interval for an unknown proportion of successes. It takes as
input the count of successes in the sample xand the count of observations in the
sample n. The computed confidence interval depends on the user-specified confidence
level.
This test is useful in determining the probability of a given number of successes that
can be expected for a given number of trials. For instance, casino examiners would use
this test to determine if observed payouts for one slot machine demonstrate a
consistent pay out rate.
2-Prop z Interval (zInterval_2Prop)
Computes a confidence interval for the difference between the proportion of successes
in two populations (p1-p2). It takes as input the count of successes in each sample
(x1andx2) and the count of observations in each sample (n1andn2). The computed
confidence interval depends on the user-specified confidence level.
This test is useful in determining if two rates of success differ because of something
other than sampling error and standard deviation. For example, a gambler could use
this test to determine if there is an advantage in the long run by playing one game or
machine versus playing another game or machine.
Linear Reg t Intervals (LinRegtIntervals)
Computes a linear regression t confidence interval for the slope coefficient b. If the
confidence interval contains 0, this is insufficient evidence to indicate that the data
exhibits a linear relationship.
Multiple Reg Intervals (MultRegIntervals)
Computes multiple regression prediction confidence interval for the calculated y and a
confidence for y.
Stat Tests
Supported Statistical Tests
Hypothesis tests are available from the Lists&Spreadsheets application. For more
information regarding these functions, see the TI-Nspire™ Reference Guide.
Some of the wizards for Stat Tests display a Draw box. By default, the box is not
selected. Selecting the box creates a Data&Statistics work area on the page and plots
the results in that work area.
ztest (zTest)
Performs a hypothesis test for a single unknown population mean, m, when the
population standard deviation,s, is known. It tests the null hypothesis H0:m=m0
against one of the alternatives below.
• Ha:mƒm0
• Ha:m<m0
• Ha:m>m0
This test is used for large populations that are normally distributed. The standard
deviation must be known.
This test is useful in determining if the difference between a sample mean and a
population mean is statistically significant when you know the true deviation for a
population.
ttest (tTest)
Performs a hypothesis test for a single unknown population mean, m, when the
population standard deviation, s, is unknown. It tests the null hypothesis H0:m=m0
against one of the alternatives below.
• Ha:mƒm0
• Ha:m<m0
• Ha:m>m0
This test is similar to a z-test, but is used when the population is small and normally
distributed. This test is used more frequently than the z-test because small sample
populations are more frequently encountered in statistics than are large populations.
This test is useful in determining if two normally distributed populations have equal
means, or when you need to determine if a sample mean differs from a population
mean significantly and the population standard deviation is unknown.
Lists&Spreadsheet Application 468
469 Lists&Spreadsheet Application
2-Sample z Test (zTest_2Samp)

1-Prop z Test tests the null hypothesis H0:prop=p0against one of the alternatives
below.
• Ha: propƒp0
• Ha: prop<p0
• Ha: prop>p0
This test is useful in determining if the probability of the success seen in a sample is
significantly different from the probability of the population or if it is due to sampling
error, deviation or other factors.
2-Prop z Test (zTest_2Prop)
Computes a test to compare the proportion of successes (p1and p2) from two
populations. It takes as input the count of successes in each sample (x1and x2) and
the count of observations in each sample (n1and n2). 2-Prop z Test tests the null
hypothesis H0:p1=p2(using the pooled sample proportion Ç) against one of the
alternatives below.
• Ha: p1ƒp2
• Ha: p1<p2
• Ha: p1>p2
This test is useful in determining if the probability of success seen in two samples is
equal.
c2GOF (c2GOF)
Performs a test to confirm that sample data is from a population that conforms to a
specified distribution. For example, c2GOF can confirm that the sample data came
from a normal distribution.
c22-way Test (c22way)
Computes a chi-square test for association on the two-way table of counts in the
specified Observed matrix. The null hypothesis H0for a two-way table is: no
association exists between row variables and column variables. The alternative
hypothesis is: the variables are related.
2-Sample FTest (FTest_2Samp)
Computes an F-test to compare two normal population standard deviations (s1and
s2). The population means and standard deviations are all unknown. 2-Sample FTest,
which uses the ratio of sample variances Sx12/Sx22, tests the null hypothesis
H0:s1=s2against one of the alternatives below.
• Ha:s1ƒs2
• Ha:s1<s2
• Ha:s1>s2
Below is the definition for the 2-SampleFTest.

bound is selected to achieve the preceding integral’s equality relationship.
Linear Reg t Test (LinRegtTest)

the correlation coefficient rfor the equation y=a+bx. It tests the null hypothesis
H0:b=0 (equivalently, r=0) against one of the alternatives below.
• Ha:bƒ0 and rƒ0
• Ha:b<0 and r<0
• Ha:b>0 and r>0
Multiple Reg Tests (MultRegTest)
Computes a linear regression on the given data, and provides the F test statistic for
linearity.
For more information, see the TI-Nspire™ Reference Guide.
ANOVA (ANOVA)
Computes a one-way analysis of variance for comparing the means of 2 to 20
populations. The ANOVA procedure for comparing these means involves analysis of the
variation in the sample data. The null hypothesis H0:m1=m2=...=mkis tested against the
alternative Ha: not all m1...mkare equal.
The ANOVA test is a method of determining if there is a significant difference
between the groups as compared to the difference occurring within each group.
This test is useful in determining if the variation of data from sample-to-sample shows
a statistically significant influence of some factor other than the variation within the
data sets themselves. For example, a box buyer for a shipping firm wants to evaluate
three different box manufacturers. He obtains sample boxes from all three suppliers.
ANOVA can help him determine if the differences between each sample group are
significant as compared to the differences within each sample group.
ANOVA 2-Way (ANOVA2way)
Computes a two-way analysis of variance for comparing the means of two to 20
populations. A summary of results is stored in the stat.results variable.
The two-way ANOVA analysis of variance examines the effects of two independent
variables and helps to determine if these interact with respect to the dependent
variable. (In other words, if the two independent variables do interact, their combined
effect can be greater than or less than the impact of either independent variable
additively.)
This test is useful in evaluating differences similar to the ANOVA analysis but with the
addition of another potential influence. To continue with the ANOVA box example, the
two-way ANOVA might examine the influence of box material on the differences seen.
Selecting an Alternative Hypothesis (ƒ< >)
Most of the inferential stat editors for the hypothesis tests prompt you to select one of
three alternative hypotheses.
• The first is a ƒalternative hypothesis, such as mƒm0 for the zTest.
• The second is a <alternative hypothesis, such as m1<m2 for the 2-SampletTest.
• The third is a >alternative hypothesis, such as p1>p2 for the 2-PropzTest.
To select an alternative hypothesis, move the cursor to the appropriate alternative, and
then press Enter.
Selecting the Pooled Option
Pooled (2-SampletTest and 2-SampletInterval only) specifies whether the variances
are to be pooled for the calculation.
• Select No if you do not want the variances pooled. Population variances can be
unequal.
• Select Yes if you want the variances pooled. Population variances are assumed to
be equal.
To select the Pooled option, select Yes from the drop-down list.
Working with Function Tables

Basic Operations in Data& Statistics
The Data& Statistics application lets you explore and visualise data and graph
inferential statistics. The Lists& Spreadsheet application can work in conjunction with
the Data& Statistics application. The Lists& Spreadsheet Summary Plot and Quick
Graph tools automatically add a Data& Statistics application to show plots. A list that
you create in a problem (using the Lists& Spreadsheet or Calculator applications) can
be accessed as a variable in any TI-Nspire™ application in that problem.
Changing Data& Statistics Settings
1. From the Settings menu, select Settings.
2. Select the settings that you want to use.
•Display Digits. Lets you select the display format for numeric labels in the
current document. Select Auto to automatically follow the setting in the

certain regression equations.
-r2is displayed for Linear (mx+b), Linear (a+bx), Power, Exponential and
Logarithmic regressions.
-R2is displayed for Quadratic, Cubic and Quartic regressions.
Using the Default Caseplot
The Data& Statistics application plots numeric and string (categorical) data from
variables. When you add a Data& Statistics application to a problem that includes
lists, a default caseplot displays on the work area.
The caseplot is like having a stack of cards with information on them and scattering
the cards randomly on a table. You can click a dot to see the information on that
“card”. You can drag a dot to “group” the “cards” by the caption variable.
▶Click the variable name displayed after Caption to use the caseplot.
- Choose <None> to remove the default caseplot.
- Choose the name of a variable to have it replace the current caseplot variable.
- Hover over any data point to see the summary information.
- Drag any data point toward an axis to see how the points group.
- Activate the Graph Trace tool and press ◄or►to move across points.
When you add a variable to either axis, the plot for that variable replaces the default
caseplot. The default caseplot redisplays if you remove the plotted variable from each
axis.
Using the Context Menu
The context menu provides access to the tools most commonly used with the selected
object. The context menu displays different options depending on the active object and
the task you are performing.
▶To open the context menu for an object.
Windows®: Right-click the object.
Mac®: Hold “and click the object.
Handheld: Point to the object and press / b.

Selecting Data and Displaying Summary Information
When you hover over part of a plot, the Data& Statistics application displays summary
information for the data it represents.
1. Hover at an area of interest in a plot to display data values or summary
information. For example, you can hover over the centre of a box plot to display the
median summary data.
2. Click once to select a representation of data in a plot.
Data points are shown with a bold outline to indicate selection. You can click a
point a second time to deselect it, or click additional points to add to the selection.
Plotting Variables
To plot variables, start with a problem that includes a Data& Statistics application and
lists created in the Lists& Spreadsheet application or the Calculator application.
1. Click the Add Variable region near the centre of an axis.
If no variable is plotted on the axis, the tooltip Click or Enter to add variable
displays.
2. Click the tooltip Click or Enter to add variable.
A list displays the names of available variables.
3. Click the name of the variable to plot.
Note: By convention, the independent variable is shown on the x-axis.
The default plot for one variable is a dot chart. The data points in the default
caseplot reposition to represent the elements of the selected variable in a dot
chart.
4. (Optional) Click the Add Variable region near the centre of the remaining axis to
plot a second variable.
The default plot for two variables is a scatter plot. The data points shift to
represent the elements of both variables as a scatter plot.
5. (Optional) Repeat Steps 1-3 to choose additional variables to plot on the vertical
axis.
The name of each variable that you add is appended to the label on the axis. The
default data point shape changes to help you distinguish data, and a legend is
displayed to identify the shapes.
6. Change, analyse or explore the plotted data.
- Remove or change the variable on an axis by clicking the Add Variable region
again.
- View the plotted data in another supported plot type by selecting a tool from
the Plot Typesmenu.
- Choose the Graph Trace tool on the Analyse menu and press ◄or►to move
across the data points in the plot.
- The lists that you plot as variables can include incomplete or missing cases. (A
case is the data contained in a row of cells in the Lists& Spreadsheet
application.) The Lists& Spreadsheet application displays a void as an
underscore (“_”), and Data& Statistics plots no data point for a void cell.
Manipulating Plotted Data
You can manipulate data points on the Data& Statistics work area to explore their
effects. For example, you could explore how a specific group of values affects the
median.
Data&Statistics Application 478
479 Data&Statistics Application
You can move a data point only in directions allowed by its definition. If a list is defined
with a formula in Lists& Spreadsheet, the points in Data& Statistics may not move
because of the formula’s restrictions. For example, you can manipulate a plot that
represents the result of y=x, but you can only move along a line.
You cannot move points that represent data in a locked variable or data that represents
a categorical value.
1. On the Data& Statistics work area, click a representation of data—such as a
histogram bin or a whisker of a box plot—that is not locked or restricted by a
formula.
The pointer changes to an open hand to show that the data can be moved.
2. Drag the selection to explore how different values of the point affect the plot.
Handheld: Press / a to grab, and then swipe or use the arrow keys to drag.
As you drag, the changing value displays on the work area.
Overview of Raw and Summary Data
You can create plots directly from raw data or from a summary table.
Raw data Summary table for eye colour based on raw data
• Raw data consists of a single list, such as a list of eye colours. When you create a
plot of raw data, Data&Statistics counts the occurrences for you. Plotting raw
data directly gives you flexibility in analysing it.
• A summary table consists of two lists, such as eye colours (the XorYList) and
counts of eye-colour occurrences (the Summary List). For more information, see
Using Lists&Spreadsheet chapter.
Working with Numeric Plot Types
Plots can represent the data from a variable in a variety of ways. Choosing the
appropriate plot can help you visualise the data. For example, you may be able to
observe the shape and spread of the data in one plot type and another type may be
useful for determining the best method for statistically evaluating data.
Creating Dot Plots
Dot plots, also known as dot-frequency plots, represent one-variable data. Dot plots are
the default plot type for numeric data. When you plot a variable as a dot plot, one dot
represents each value in the list. Each dot displays on the axis at a point that
correspond to the value.
1. To create a dot plot, click the Add Variable region in the center of an axis and click
the name of a numeric variable. For more information, see Plotting Variables.
2. (Optional) To split a dot plot by category, click the Add Variable region on the other
axis and choose the list that contains the corresponding category data.
3. (Optional) To plot multiple dot plots, choose Add X Variable on the Plot Properties
menu and click a numeric variable from the list that displays.
A second dot plot appears on the work area and the name of the plotted variable is
added to both axis labels.
4. Explore the plotted data.
- Hover over a data point to display data values.
Data&Statistics Application 480
481 Data&Statistics Application
- Drag a dot to move it. As you move a point, the values associated with it
change on the work area display and in the list for the variable.
- Activate the Graph Trace tool and press ◄or►to move across the data
points in the plot in list order. Points enlarge and display a bold outline as you
move across them in Trace mode.
Creating Box Plots
The Box Plot Tool plots one-variable data in a modified box plot. “Whiskers” extend
from each end of the box, either to 1.5 times the interquartile range or to the end of
the data, whichever comes first. Points that are a width of 1.5*Interquartile Range
past the quartiles plot individually, beyond the whiskers. These points are the potential
outliers. When no outliers exist, x-min and x-max are the prompt for the end of each
whisker.
Box plots are useful for comparing two or more sets of data that use the same scale. If
a dataset is large, a box plot can also be useful in exploring data distribution.
1. Click the Add Variable region in the centre of an axis. The default plot for one
numeric variable is a dot plot. For more information, see Plotting Variables.
Note: If two variables are plotted in the work area, you can create a dot plot by
removing one variable. Choose RemoveXVariable or RemoveYVariable from the
Plot Types menu.
2. On the Plot Types menu, click Box Plot.
A modified box plot displays on the Data&Statistics work area.
Note: You can split a box plot by category by adding a list that contains
corresponding categorical data to the y-axis.
3. (Optional) To add additional variables for comparing box plots on the same axis,
click Add X Variable on the Plot Properties menu.
For example, you can use multiple box plots to compare the distributions of sample
proportions. In the example, true proportion is .5 and sample size varies from n=20
to n=40 to n=90.
Notes:
- You can create a box plot with frequency by choosing Add X Variable or Add Y
Variable on the Plot Properties menu.
- You can specify a variable multiple times as you choose variables to plot as box
plots.
- The variable used to provide frequency information is added to the label on the
horizontal axis in the format: x_variablename{frequencylist_name}.
Data&Statistics Application 482
483 Data&Statistics Application
4. Point and click the regions of the box plot to explore and analyse the data it
represents.
- Hover over a region or over a whisker to display the details for the portion of
the plot that interests you. The label for the quartile that corresponds to your
selection is displayed.
- Click a region of the box plot to select the data points or whiskers. Click again
to remove the selection.
- You can select any box plot that does not include frequency data and choose
Dot Plot on the context menu to change the plot type.
- Drag a selection to move it and explore other possibilities for the data.
- Use the arrow keys to move a data point one pixel at a time.
- Activate the Graph Trace tool and press ◄or►to move across dots and
regions of the plot. As the trace cursor moves, the values for Q1, the median,
Q3 and whisker ends/outliers are displayed.
5. Change the plot from a modified box plot to a standard box plot by choosing Extend
Box Plot Whiskers on the Plot Properties menu.
The box plot is redrawn as a standard box plot with extended whiskers.
The standard box plot’s whiskers use the minimum and maximum points in the
variable and outliers are not identified. The whiskers on the plot extend from the
minimum data point in the set (x-min) to the first quartile (Q1) and from the third
quartile (Q3) to the maximum point (x-max). The box is defined by Q1, Med
(median), and Q3.
Note: You can click Show Box Plot Outliers on the Plot Properties menu to return to
the modified box plot.
Plotting Histograms
A histogram plots one-variable data and depicts the distribution of data. The number
of bins displayed depends on the number of data points and the distribution of these
points. A value that occurs on the edge of a bin is counted in the bin to the right.
Creating a Histogram from Raw Data
1. Create the list that you want to plot as a histogram. For example, you can enter or
collect data as a named list on a Lists&Spreadsheet page.
2. On a Data&Statistics page, click the x or y axis, and select your list as the data to
plot.
3. From the Plot Types menu, click Histogram.
The data forms the bins of a histogram, with Frequency plotted by default on the
unselected axis.
4. Explore the data.
- Hover over a bin to see the information for that bin.
- Click a bin to select it. Click the bin again to deselect it.
- Drag the side of a bin to adjust bin width and number of bins.
Note: The bins are not adjustable in categorical plots or plots in which you
choose variable bin widths.
- On the Analyse menu, click Graph Trace and press ◄or►to cycle through the
bins and display their values.

Scale.
2. Choose the format for the scale of the histogram.
-Frequency - displays data based upon the number of values that occur within
each bin. This is the default data representation.
-Percent - displays data in the histogram by each group’s percent value of the
whole data set.
-Density - displays data based upon the density of each group within the data
set.
Creating a Histogram with Frequency or Summary Data
1. On a Lists&Spreadsheet page, create two lists: one containing the “bins”, such as
heights in a population (ht), and the other containing the frequencies of those
heights (freq).
2. On a Data&Statistics page, access the context menu on the x axis, and click Add X
Variable with Summary List.
3. Select ht as the X List and freq as the Summary List.
Note: It is up to you to set the data and bins in a meaningful way when using
summary data.
Setting Equal Bin Widths
By default, bin widths are set to equal. You can specify the width and alignment of
equal-width bins.
1. On the Plot Properties menu, click HistogramProperties > BinSettings and choose
Equal Bin Width.
The Equal Bin Width Settings dialogueue box opens.
2. Type values to set Width and Alignment of the bins.
3. Click OK to apply the changes and redraw the bins.
Both the data represented by the bins and the value you type for the alignment
affect the placement of bins on the scale.
Setting Variable Bin Widths
You can set variable bin widths based on a list of bin boundaries.
1. Create a named list containing boundary values.
For example, a boundary list defined as {60,70,100,110} will create bins at 60 to
70, 70 to 100 and 100 to 110.
Note: The data must fall within the specified bin widths. For example, a data point
of 115 would be outside the bins in the above list, and you would receive a
Data/Bin Location Mismatch error.
2. On the Plot Properties menu, click HistogramProperties > BinSettings and choose
Variable Bin Width.
The Variable Bin Width Settings dialogue box opens.
Data&Statistics Application 486
487 Data&Statistics Application
3. Select your boundary list as the List of Bin Boundaries.

• Leading digits are treated as coefficients and are shown at full size. Numbers that
follow an element or a closed parenthesis are converted to subscripts.
• The equals “=” symbol is converted to a yields “&” symbol.
Notes:
• Equations in a chem box cannot be evaluated or balanced.
• Element capitalisation may not work in every situation. For example, to enter
carbon dioxide, CO2, you must manually capitalise theO. Otherwise, typing “co”
would result in“Co”, the symbol for cobalt.

Widgets
All work that you create and save using TI-Nspire™ applications is stored as a
document, which you can share with others using TI-Nspire™ software, a TI-Nspire™
handheld, or the TI-Nspire™ App for iPad®. You save these TI-Nspire™ documents as
.tns files.
A Widget is a .tns document that is stored in your MyWidgets folder.
You can use Widgets to:
• Easily access text files
• Insert and run scripts (such as the pre-loaded widget example: Stopwatch.tns)
• Quickly insert a saved problem into a document
When you add a Widget, TI-Inspire™ CX extracts only the first page of the selected .tns
file, and inserts it into your open document.
Creating a Widget
A document is regarded as a Widget when it is saved or copied to the designated
MyWidgets folder. The default location is:
• Windows®: MyDocuments\TI-Nspire\MyWidgets.
• Mac®: Documents/TI-Nspire/MyWidgets.
• Handheld: MyWidgets
• TI-Nspire™ App for iPad® and TI-Nspire™ CASApp for iPad®: MyWidgets
If the MyWidget folder has been inadvertently deleted, you must create it before
attempting to use a Widget.
Note: When you add a Widget, TI-Inspire™ CX extracts only the first page of the
selected .tns file, and inserts it into your open document.

Libraries
What is a Library?
A library is a TI-Nspire™ document that contains a collection of variables, functions
and/or programmes that have been defined as library objects.
Unlike ordinary variables, functions and programmes, which can be used only within a
single problem (the problem in which they are defined), library objects are accessible
from any document. You can even create public library objects that appear in the
TI-Nspire™ Catalogue.
For example, suppose you have created library document matrix containing public
library function diagwithtrace() and a private library function errmsg().
Function diagwithtrace() displays the diagonal of a square matrix and calculates the
trace of the matrix. If its input is not a square matrix, the function calls errmsg(), which
should then return an appropriate error string.
You could then use the following syntax to display the diagonal and calculate the trace
of matrix mdefined in the current problem:
matrix\diagwithtrace(m)
Creating Libraries and Library Objects
A document is regarded as a library when it is saved or copied to the designated library
folder. The default location is:
• Windows®: MyDocuments\TI-Nspire\MyLib.
• Mac®: Documents/TI-Nspire/MyLib.
• Handheld: MyLib
Libraries 546
547 Libraries
If the folder has been inadvertently deleted, you must create it before attempting to
use libraries.
You can define library objects using either the Programme Editor or the Calculator
application. Library objects must be defined with a Define command and must reside
in the first problem of a library document.
Note: If you use the Programme Editor to define a library function or programme, you
must store the object and also save the document. Saving the document does not
automatically store the object. For more information, see Programming.
Naming restrictions apply to library documents and library objects.
• A library document name must be a valid variable name between 1 and 16
characters long, and it must not contain a period or begin with an underscore.
• A library object name must be a valid variable name between 1 and 15 characters
long. It must not contain a period and must not begin with an underscore.
Private and Public Library Objects
When you define a library object, you designate it as private (LibPriv) or public (LibPub).
Define a=5
a is not a library object.
Define LibPriv b={1,2,3}
b is a private library object.
Define LibPub func1(x)=x^2 - 1
func1 is a public library object.
APrivate library object does not appear in the Catalogue, but you can access it by
typing its name. Private objects serve well as building blocks that perform basic, low-
level tasks. Typically, private library objects are called upon by the public functions and
programmes.
APublic library object appears in the Catalogue’s library tab after you refresh the
libraries. You can access a public library object through the Catalogue or by typing its
name.
Mac® only: In version 1.4 of the software, a library document name cannot contain
extended characters, such as Ö, á or ñ.
Note: In library programmes and functions defined as public, a comment line (©)
immediately following the Prgm or Func line is automatically displayed as help in the
Catalogue. You could, for example, show a syntax reminder there.
Using Short and Long Names
Anytime you are in the same problem where an object is defined, you can access it by
entering its short name (the name given in the object’s Define command). This is the
case for all defined objects, including private, public and non-library objects.
You can access a library object from any document by typing the object’s long name. A
long name consists of the name of the object’s library document followed by a
backslash “\” followed by the name of the object. For example, the long name of the
object defined as func1 in the library document lib1 is lib1\func1. To type the “\”
character on the handheld, press g p.
Note: If you cannot remember the exact name or the order of arguments required for a
private library object, you can open the library document or use the Programme Editor
to view the object. You also can use getVarInfo to view a list of objects in a library.
Using Library Objects
Before using a library variable, function or programme, make sure that these steps
have been followed:
• The object has been defined with the Define command, and the command
specifies either the LibPriv or LibPub attribute.
• The object resides in the first problem of a library document. The document must
reside in the designated library folder and must meet the naming requirements.
• If you defined the object using the Programme Editor, it has been stored using
Check Syntax & Store from the Programme Editor menu.
• The libraries have been refreshed.
Refreshing the Libraries
▶Refresh libraries to make the library objects available to your documents.
- From the Tools menu, click Refresh Libraries.
Handheld: Press / b and click Refresh Libraries.
Using a Public Library Object
1. Refresh the libraries.
2. Open the TI-Nspire™ application in which you want to use the variable, function or
programme.
Note: All applications can evaluate functions, but only the Calculator and Notes
applications can run programmes.
3. Open the Catalogue and use the library tab to find and insert the object.
4. If arguments are required, type them inside the parentheses.
Using a Private Library Object
1. Refresh the libraries.
Libraries 548
549 Libraries
2. Open the TI-Nspire™ application in which you want to use the variable, function or
programme.
Note: All applications can evaluate functions, but only the Calculator and Notes
applications can run programmes.
3. Type the name of the object, such as lib1\func1().
In case of a function or programme, always follow the name with parentheses. To
type the “\” character on the handheld, press g p.
4. If arguments are required, type them inside the parentheses.
Creating Shortcuts to Library Objects
You can make the objects in a library more easily accessible by using libShortcut() to
create shortcuts to them. This creates a variable group in the current problem that
contains references to all the objects in the specified library document. You can choose
to include or exclude the private library objects.
For example, suppose the library document linalg contains functions named clearmat,
cofactor, gausstep, help, inversestep, kernelbasis, rank and simultstep. Executing
libShortcut(“linalg”,“la”)would create a variable group containing the following
members:
la.clearmat
la.cofactor
la.gausstep
la.help
la.inversestep
la.kernelbasis
la.rank
la.simultstep
You can refer to those library objects from within the current problem by typing their
variable names or by selecting them from the Variables menu.
For more details about using libShortcut(), see the Reference Guide.
Included Libraries
To help you get started with libraries, the TI-Nspire™ Software installation includes a
library document with useful Linear Algebra functions. The library is named linalg or
linalgCAS and is installed in the designated library folder.
Note: Updating the handheld’s operating system or reinstalling the computer software
places all included libraries in the default folder. If you have edited an object in an
included library or replaced an included library with your own document of the same
name, updating or reinstalling will overwrite your changes. This could also happen
after batteries are replaced or the handheld system is reset.
Restoring an Included Library
If you inadvertently delete or overwrite an included library, you can restore it from the
installation DVD.
1. Open the DVD, and navigate to the libs folder.
2. Identify the library file to restore, such as linalg.tns or linalgCAS.tns for the linear
algebra library.
3. Copy the file.
- Windows®: Copy the file to your designated library folder. The default location
is MyDocuments\TI-Nspire\MyLib.
- Mac®: Copy the file to your designated library folder. The default location is
Documents/TI-Nspire/MyLib.
- Handheld: Connect the handheld to your computer, open the TI-Nspire™
software, and copy the library file to the handheld’s MyLib folder.
4. Activate the new library objects.
- From the TI-Nspire™ Software Tools menu, click Refresh Libraries.
Handheld:Press / b, and click Refresh Libraries.

Using Short and Long Names
Anytime you are in the same problem where an object is defined, you can access it by
entering its short name (the name given in the object’s Define command). This is the
case for all defined objects, including private, public and non-library objects.
You can access a library object from any document by typing the object’s long name. A
long name consists of the name of the object’s library document followed by a
backslash “\” followed by the name of the object. For example, the long name of the
object defined as func1 in the library document lib1 is lib1\func1. To type the “\”
character on the handheld, press g p.
Note: If you cannot remember the exact name or the order of arguments required for a
private library object, you can open the library document or use the Programme Editor
to view the object. You also can use getVarInfo to view a list of objects in a library.
Using a Public Library Programme or Function
1. Make sure you have defined the object in the document’s first problem, stored the
object, saved the library document in the MyLib folder, and refreshed the libraries.
2. Open the TI-Nspire™ application in which you want to use the programme or
function.
Note: All applications can evaluate functions, but only the Calculator and Notes
applications can run programmes.
3. Open the Catalogue and use the library tab to find and insert the object.
—or—
Type the name of the object. In the case of a programme or function, always
follow the name with parentheses.
libs2\func1()
4. If the programme or function requires you to supply one or more arguments, type
the values or variable names inside the parentheses.
libs2\func1(34,power)
5. Press ·.
Using a Private Library Programme or Function
To use a Private library object, you must know its long name. For example, the long
name of the object defined as func1 in the library document lib1 is lib1\func1.
Note: If you cannot remember the exact name or the order of arguments required for a
private library object, you can open the library document or use the Programme Editor
to view the object.

Editor, select GoTo. The cursor appears at the command where the break occurred.
Getting Values into a Program
You can choose from several methods to supply the values that a function or program
uses in calculations.
Embedding the Values Within the Program or Function
This method is useful primarily for values that must be the same each time the
program or function is used.
1. Define the program.
Define calculatearea()=
Prgm
w:=3
h:=23.64
area:=w*h
EndPrgm
2. Run the program.
calculatearea() :area70.92
Getting Started with the Programme Editor 562
563 Getting Started with the Programme Editor
Letting the User Assign the Values to Variables
A program or function can refer to variables created beforehand. This method requires
users to remember the variable names and to assign values to them before using the
object.
1. Define the program.
Define calculatearea()=
Prgm
area:=w*h
EndPrgm
2. Supply the variables, and then run the program.
w:=3 : h:=23.64
calculatearea() :area70.92
Letting the User Supply the Values as Arguments
This method lets users pass one or more values as arguments within the expression
that calls the program or function.
The following program, volcyl, calculates the volume of a cylinder. It requires the user
to supply two values: height and radius of the cylinder.
1. Define the volcyl program.
Definevolcyl(height,radius) =
Prgm
Disp "Volume =", approx(p ¦ radius2¦height)
EndPrgm
2. Run the program to display the volume of a cylinder with a height of 34 mm and a
radius of 5 mm.
volcyl(34,5)Volume = 534.071
Note: You do not have to use the parameter names when you run the volcyl
program, but you must supply two arguments (as values, variables or expressions).
The first must represent the height and the second must represent the radius.
Requesting the Values from the User (Programs Only)
You can use the Request and RequestStr commands in a program to make the program
pause and display a dialogue box prompting the user for information. This method
does not require users to remember variable names or the order in which they are
needed.
You cannot use the Request or RequestStr command in a function.
1. Define the program.
Define calculatearea()=
Prgm
Request "Width: ",w
Request "Height: ",h
area:=w*h
EndPrgm
2. Run the program and respond to the requests.
calculatearea() : area
Width: 3 (3 entered as a response)
Height: 23.64(23.64 entered as a response)
70.92
Use RequestStr instead of Request when you want the program to interpret the user’s
response as a character string rather than a maths expression. This avoids requiring
the user to enclose the response in quotation marks (““).
Displaying Information
A running function or program does not display intermediate calculated results unless
you include a command to display them. This is an important difference between
performing a calculation on the entry line and performing it in a function or program.
The following calculations, for example, do not display a result in a function or
program (although they do from the entry line).
©
x:=12¦6
cos(p/4)&n
©
Displaying Information in the History
You can use the Disp command in a program or function to display information,
including intermediate results, in the history.
©
Disp 12¦6
Disp "Result:",cos(p/4)
©
Displaying Information in a Dialogue Box
You can use the Text command to pause a running program and display information in
a dialogue box. The user clicks OK to continue or clicks Cancel to stop the program.
You cannot use the Text command in a function.
©
Text "Area=" & area
©

Note: Displaying a result with Disp or Text does not store that result. If you expect to
refer later to a result, store it to a global variable.

Using Local Variables
A local variable is a temporary variable that exists only while a user-defined function is
being evaluated or a user-defined program is running.
Example of a Local Variable
The following program segment shows a For...EndFor loop (which is discussed later in
this module). The variable iis the loop counter. In most cases, the variable iis used
only while the program is running.
Local iÀ
For i,0,5,1
Disp i
EndFor
Disp i
ÀDeclares variable ias local.
Note: When possible, declare as local any variable that is used only within the program
and does not need to be available after the program stops.
What Causes an Undefined Variable Error Message?
An Undefined variable error message is displayed when you evaluate a user-defined
function or run a user-defined program that references a local variable that is not
initialized (assigned a value).
For example:
Define fact(n)=Func
Local mÀ
While n>1
n¦m&m: n–1&n
EndWhile
Return m
EndFunc
ÀLocal variable mis not assigned an initial value.
Initialize Local Variables
All local variables must be assigned an initial value before they are referenced.
Define fact(n)=Func
Local m: 1&mÀ
While n>1
n¦m&m: n–1&n
EndWhile
Return m
EndFunc
À1 is stored as the initial value for m.
Note (CAS): Functions and programs cannot use a local variable to perform symbolic
calculations.
CAS: Performing Symbolic Calculations
If you want a function or program to perform symbolic calculations, you must use a
global variable instead of a local. However, you must be certain that the global variable
does not already exist outside of the program. The following methods can help.
• Refer to a global variable name, typically with two or more characters, that is not
likely to exist outside of the function or program.
• Include DelVar within a program to delete the global variable, if it exists, before
referring to it. (DelVar does not delete locked or linked variables.)
Differences Between Functions and Programs
A function defined in the Program Editor is similar to the functions built into the
TI-Nspire™ Software.
• Functions must return a result, which can be graphed or entered in a table.
Programs cannot return a result.
• You can use a function (but not a program) within an expression. For example: 3¦
func1(3) is valid, but not 3¦prog1(3).
• You can run programs from Calculator and Notes applications only. However, you
can evaluate functions in Calculator, Notes, Lists & Spreadsheet, Graphs &
Geometry and Data & Statistics.
• A function can refer to any variable; however, it can store a value to a local variable
only. Programs can store to local and global variables.
Note: Arguments used to pass values to a function are treated as local variables
automatically. If you want to store to any other variables, you must declare them
as Local from within the function.
• A function cannot call a program as a subroutine, but it can call another user-
defined function.
• You cannot define a program within a function.
• A function cannot define a global function, but it can define a local function.

567 Getting Started with the Programme Editor
Calling One Program from Another
One program can call another program as a subroutine. The subroutine can be external
(a separate program) or internal (included in the main program). Subroutines are
useful when a program needs to repeat the same group of commands at several
different places.
Calling a Separate Program
To call a separate program, use the same syntax that you use to run the program from
the entry line.
Defining and Calling an Internal Subroutine
To define an internal subroutine, use the Define command with Prgm...EndPrgm.
Because a subroutine must be defined before it can be called, it is a good practice to
define subroutines at the beginning of the main program.
An internal subroutine is called and executed in the same way as a separate program.
Define subtest1()=
Prgm
local subtest2À
Define subtest2(x,y)=Á
Prgm
Disp x,y
EndPrgm
©Beginning of main program
For i,1,4,1
subtest2(i,I*1000) Â
EndFor
EndPrgm
ÀDeclares the subroutine as a local variable.
ÁDefines the subroutine.
ÂCalls the subroutine.
Note: Use the Program Editor’s Var menu to enter the Define and Prgm...EndPrgm
commands.
Notes about Using Subroutines
At the end of a subroutine, execution returns to the calling program. To exit a
subroutine at any other time, use Return with no argument.
A subroutine cannot access local variables declared in the calling program. Likewise,
the calling program cannot access local variables declared in a subroutine.
Lbl commands are local to the programs in which they are located. Therefore, a Goto
command in the calling program cannot branch to a label in a subroutine or vice versa.
Avoiding Circular-Definition Errors
When evaluating a user-defined function or running a program, you can specify an
argument that includes the same variable that was used to define the function or
create the program. However, to avoid circular-definition errors, you must assign a
value for variables that are used in evaluating the function or running the program.
Forexample:
x+1&xÀ
– or –
For i,i,10,1
Disp iÀ
EndFor
ÀCauses a Circular definition error message if x or i does not have a value. The error
does not occur if x or i has already been assigned a value.
Controlling the Flow of a Function or Program
When you run a program or evaluate a function, the program lines are executed in
sequential order. However, some commands alter the program flow. For example:
• Control structures such as If...EndIf commands use a conditional test to decide
which part of a program to execute.
• Loop commands such as For...EndFor repeat a group of commands.
Using If, Lbl and Goto to Control Program Flow
The If command and several If...EndIf structures let you execute a statement or block
of statements conditionally, that is, based on the result of a test (such as x>5). Lbl
(label) and Goto commands let you branch or jump, from one place to another in a
function or program.
The If command and several If...EndIf structures reside on the Program Editor’s Control
menu.
When you insert a structure such as If...Then...EndIf, a template is inserted at the
cursor location. The cursor is positioned so that you can enter a conditional test.
Getting Started with the Programme Editor 568
569 Getting Started with the Programme Editor
If Command
To execute a single command when a conditional test is true, use the general form:
If x>5
Disp "x is greater than 5"À
Disp xÁ
ÀExecuted only if x>5; otherwise, skipped.
ÁAlways displays the value of x.
In this example, you must store a value to x before executing the Ifcommand.
If...Then...EndIf Structures
To execute one group of commands if a conditional test is true, use the structure:
If x>5 Then
Disp "x is greater than 5"À
2¦x&xÀ
EndIf
Disp xÁ
ÀExecuted only if x>5.
ÁDisplays the value of:
2x if x>5
x if x{5
Note: EndIf marks the end of the Then block that is executed if the condition is true.
If...Then...Else...EndIf Structures
To execute one group of commands if a conditional test is true and a different group if
the condition is false, use this structure:
If x>5 Then
Disp "x is greater than 5"À
2¦x&xÀ
Else
Disp "x is less than or equal to 5"Á
5¦x&xÁ
EndIf
Disp xÂ
ÀExecuted only if x>5.
ÁExecuted only if x{5.
ÂDisplays value of:
2x if x>5
5x if x{5
If...Then...ElseIf... EndIf Structures
A more complex form of the If command lets you test for multiple conditions. Suppose
you want a program to test a user-supplied argument that signifies one of four
options.
To test for each option (IfChoice=1, If Choice=2 and so on), use the
If...Then...ElseIf...EndIf structure.
Lbl and Goto Commands
You can also control the flow by using Lbl (label) and Goto commands. These
commands reside on the Program Editor’s Transfers menu.
Use the Lbl command to label (assign a name to) a particular location in the function
or program.
Lbl labelName name to assign to this location (use the
same naming convention as a variable
name)
You can then use the Goto command at any point in the function or program to branch
to the location that corresponds to the specified label.
Goto labelName specifies which Lbl command to branch
to
Because a Goto command is unconditional (it always branches to the specified label),
it is often used with an If command so that you can specify a conditional test. For
example:
If x>5
Goto GT5À
Disp x
--------
-------- Á
Lbl GT5
Disp "The number was > 5"
ÀIf x>5, branches directly to label GT5.
ÁFor this example, the program must include commands (such as Stop) that prevent
Lbl GT5 from being executed if x{5.
Getting Started with the Programme Editor 570
571 Getting Started with the Programme Editor
Using Loops to Repeat a Group of Commands
To repeat the same group of commands successively, use one of the loop structures.
Several types of loops are available. Each type gives you a different way to exit the
loop, based on a conditional test.
Loop and loop-related commands reside on the Program Editor’s Control and Transfers
menus.
When you insert one of the loop structures, its template is inserted at the cursor
location. You can then begin entering the commands that will be executed within the
loop.
For...EndFor Loops
AFor...EndFor loop uses a counter to control the number of times the loop is repeated.
The syntax of the For command is:
Note: The ending value can be less than the beginning value, provided the increment is
negative.
For variable,begin,end [, increment]
À Á Â Ã
ÀVariable used as a counter
ÁCounter value used the first time For is executed
ÂExits the loop when variable exceeds this value
ÃAdded to the counter each subsequent time For is executed (If this optional value is
omitted, the increment is 1.)
When For is executed, the variable value is compared to the end value. If variable
does not exceed end, the loop is executed; otherwise, control jumps to the command
following EndFor.
Note: The For command automatically increments the counter variable so that the
function or program can exit the loop after a certain number of repetitions.
At the end of the loop (EndFor), control jumps back to the For command, where the
variable is incremented and compared to end.
For example:
For i,0,5,1
Disp iÀ
EndFor
Disp iÁ
ÀDisplays 0, 1, 2, 3, 4, and 5.
ÁDisplays 6. When variable increments to 6, the loop is not executed.
Note: You can declare the counter variable as local if it does not need to be saved after
the function or program stops.
While...EndWhile Loops
AWhile...EndWhile loop repeats a block of commands as long as a specified condition
is true. The syntax of the While command is:
While condition
When While is executed, condition is evaluated. If condition is true, the loop is
executed; otherwise, control jumps to the command following EndWhile.
Note: The While command does not automatically change the condition. You must
include commands that allow the function or program to exit the loop.
At the end of the loop (EndWhile), control jumps back to the While command, where
condition is re-evaluated.
To execute the loop the first time, the condition must initially be true.
• Any variables referenced in the condition must be set before the While command.
(You can build the values into the function or program, or you can prompt the user
to enter the values.)
• The loop must contain commands that change the values in the condition,
eventually causing it to be false. Otherwise, the condition is always true and the
function or program cannot exit the loop (called an infinite loop).
For example:
0&xÀ
While x<5
Disp xÁ
x+1&xÂ
EndWhile
Getting Started with the Programme Editor 572
573 Getting Started with the Programme Editor
Disp xÃ
ÀInitially sets x.
ÁDisplays 0, 1, 2, 3, and 4.
ÂIncrements x.
ÃDisplays 5. When x increments to 5, the loop is not executed.
Loop...EndLoop Loops
ALoop...EndLoop creates an infinite loop, which is repeated endlessly. The Loop
command does not have any arguments.
Typically, you insert commands in the loop that let the program exit from the loop.
Commonly used commands are: If,Exit,Goto and Lbl (label). For example:
0&x
Loop
Disp x
x+1&x
If x>5À
Exit
EndLoop
Disp xÁ
ÀAn If command checks the condition.
ÁExits the loop and jumps to here when xincrements to 6.
Note: The Exit command exits from the current loop.
In this example, the If command can be anywhere in the loop.
When the If command is: The loop is:
At the beginning of the
loop
Executed only if the condition is true.
At the end of the loop Executed at least once and repeated only if the condition
is true.
The If command could also use a Goto command to transfer program control to a
specified Lbl (label) command.
Repeating a Loop Immediately
The Cycle command immediately transfers program control to the next iteration of a
loop (before the current iteration is complete). This command works with For...EndFor,
While...EndWhile and Loop...EndLoop.
Lbl and Goto Loops
Although the Lbl (label) and Goto commands are not strictly loop commands, they can
be used to create an infinite loop. For example:
As with Loop...EndLoop, the loop should contain commands that let the function or
program exit from the loop.
Changing Mode Settings
Functions and programs can use the setMode() function to temporarily set specific
calculation or result modes. The Program Editor’s Mode menu makes it easy to enter
the correct syntax without requiring you to memorise numeric codes.
Note: Mode changes made within a function or program definition do not persist
outside the function or program.
Setting a Mode
1. Position the cursor where you want to insert the setMode function.
2. From the Mode menu, click the mode to change, and click the new setting.
The correct syntax is inserted at the cursor location. For example:
setMode(1,3)
Debugging Programs and Handling Errors
After you write a function or program, you can use several techniques to find and
correct errors. You can also build an error-handling command into the function or
program itself.
If your function or program allows the user to select from several options, be sure to
run it and test each option.
Getting Started with the Programme Editor 574
575 Getting Started with the Programme Editor
Techniques for Debugging
Run-time error messages can locate syntax errors but not errors in program logic. The
following techniques may be useful.
• Temporarily insert Disp commands to display the values of critical variables.
• To confirm that a loop is executed the correct number of times, use Disp to display
the counter variable or the values in the conditional test.
• To confirm that a subroutine is executed, use Disp to display messages such as
“Entering subroutine” and “Exiting subroutine” at the beginning and end of the
subroutine.
• To stop a program or function manually,
- Windows®: Hold down the F12 key and press Enter repeatedly.
- Mac®: Hold down the F5 key and press Enter repeatedly.
- Handheld: Hold down the ckey and press ·repeatedly.
Error-handling Commands
Command Description
Try...EndTry Defines a block that lets a function or program execute a command and,
if necessary, recover from an error generated by that command.
ClrErr Clears the error status and sets system variable errCode to zero. For an
example of using errCode, see the Try command in the Reference
Guide.
PassErr Passes an error to the next level of the Try...EndTry block.

When you open a document using the emulator, you can only open documents that are
in the folder displayed on the emulator (usually the My Documents folder, unless you
specified a different folder in your TI-SmartView™ settings). When you open a
document using the menu path, you can browse to find any TI-Nspire™ document on
your computer or network. If you open a document using the emulated handheld, it
replaces the document that was previously open.
Note: If the number of characters in the document’s file path name exceeds 256
characters, the document cannot be opened and an error message is displayed. To
avoid this error, keep file and folder names short or move files up in the file path.

Writing Lua Scripts
The Script Editor allows you to create and deliver dynamically linked simulations,
powerful and flexible utilities and other educational content for exploring maths and
science concepts. When you open a document containing a script, the script runs
automatically as programmed. To see the running script application, the page
containing the script application must be active.
The Script Editor is directed toward teachers and other authors who are comfortable
working in a Lua scripting environment. Lua is a powerful, fast, lightweight scripting
language that is fully supported in TI-Nspire™ and PublishView™ documents.
Documents containing script applications can be opened on TI-Nspire™ handhelds. The
script application runs on a handheld, but you cannot view or edit the script.
Note these resources for using the Script Editor and creating scripts:
• Press F1 to access the TINspire™ help, which includes the Script Editor help.
• Press F2 for additional TI-Nspire™ resources such as scripting samples and a link to
the TI-Nspire™ Scripting API library. (This information is also available at
education.ti.com/nspire/scripting.)
• Go to lua.org for more information about Lua.
Overview of the Script Editor
With the Script Editor, you can insert, edit, save, run, and debug script applications
inTI-Nspire™ (.tns files) and Publishview™ (.tnsp files) documents.
• Script applications function within documents, problems, and pages the same way
that other TI-Nspire™ applications do.
• When you create a new document or open an existing document, you can insert or
edit a script application within a page or within a work area of a split page.
• In a split page layout, you can add a script application to each work area of a page.
A page can be split into a maximum of four quadrants.
• Images can be added to script applications. See the Inserting Images section.
• All work done in the Script Editor is lost if you close the TI-Nspire™ or
PublishView™ document without saving it.
Exploring the Script Editor Interface
The Script Editor window opens when you insert a new script application or edit an
existing script application in a TI-Nspire™ or PublishView™ document.
Select options for creating new scripts or editing scripts from the Insert menu in the
Documents Workspace when a document is open.

Setting Minimum API Level
Each release of the T-Nspire™ software includes API support for a specific set of Lua
scripting features. Setting the minimum API level for a script lets you specify a
minimum set of features that you require for your script.
If a user tries to run the script on a system that does not meet the script's minimum
API level, a message notifies the user and prevents the script from running.
To Set the Minimum API Level for a Script:
1. Determine the minimum level that you want your script to require.
- Setting the level too low for the script's feature set can result in a script error
on older software.
- Setting the level too high can result in the script refusing to start on older
software that supports the feature set.
2. On the Script Editor File menu, select Set Minimum API Level.
3. In the dialogue box, type the minimum level using the format major.minor. For
example, you might type 2.3.

Find pH derivative settings using a calculated column.
The Vernier DataQuest™ application can determine a numeric derivative from a list of
data with respect to another list of data. The data can be collected using sensors, input
manually, or linked with other applications. The numerical derivative is found using a
calculated column.
To determine the numerical 1st derivative of List B with respect to List A, enter the
following expression in the Column Options dialogue:
derivative(B,A,1,0) or derivative(B,A,1,1)
To determine the numerical 2nd derivative of List B with respect to List A, enter the
following expression:
derivative(B,A,2,0) or derivative (B,A,2,1)
The last parameter is either 0 or 1 depending on the method you are using. When it is
0, a weighted average is used. When it is 1, a time shifted derivative method is used.
Note: The first derivative calculation (weighted average) is what the Tangent tool uses
to display the slope at a data point when examining data. (Analyse > Tangent).
Note: The derivative calculation is completely row based. It is recommended that your
List A data be sorted in ascending order.
1. Click Options > Derivative Settings.
The Settings dialogue box opens.
