Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 17 of 64 Exercise 2: Storing Values as Variables You can store a value as a named variable and then use the name to refer to that value in subsequent Math Boxes and graphs. When TI InterActive! evaluates an expression containing the name, it substitutes the value stored under that name. This exercise shows you how to: 18 ¦ Define a variable and assign a value to it. ¦ Display a variable’s value in a document. ¦ Remove a variable. ¦ Perform symbolic calculations. ¦ Reposition TI InterActive! objects in a document. ¦ Reset all variables. Getting Started with TI InterActive! TII_GettingStarted.doc Getting Started with TI InterActive! Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 18 of 64 Storing a value in a variable TIP: If you have changed a document and then attempt to create a new document, TI InterActive! gives you the option to save the first document before proceeding. This example creates a variable named num and stores the result of the expression 5+8 3 in that variable. 1. On the TI InterActive! toolbar, click the New button start a new, blank document. 2. Click the Math Box button to to insert a new Math Box. 3. Type the variable name num and then type := (both characters are required from the keyboard), or click the Math Palette. on num := 4. Type the expression 5+8^3. The result—not the expression— will be stored in num. This means: Let the variable “num” equal the result of 5+8 3 . num := 5+8^3 5. Press Enter on the computer keyboard. TI InterActive! creates the variable num and stores the result there. Checking a variable’s value You can check the value of a variable by entering its name as the entry in a subsequent Math Box. 1. Click the Math Box button necessary. to insert a new Math Box, if 2. Type the variable name num and press Enter on the computer keyboard. The value currently stored in num is displayed as the result.

Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 19 of 64 Using a variable in a calculation After storing a value in a variable, you can use the variable name in an expression as a substitute for the stored value. 1. Click the Math Box button necessary. to insert a new Math Box, if 2. Type 4*25*num^2 in the Math Box, and press Enter. TI InterActive! substitutes 517, the value assigned to num, and evaluates the expression. 3. Type 4*25*nonum^2 in a Math Box, and press Enter. Because the variable nonum has not been defined, it is treated algebraically in the result. Updating a variable 20 If you want to update a variable with the result of a calculation, you must store the result explicitly. Entry Result a := 2 2 a^3 8 a 2 a := a^3 8 a 8 a^2 N> a 64 a 64 Comment Result not stored in variable a. Variable a updated with result. Variable a updated with result.

Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 20 of 64 Types of variables You can store any TI InterActive! data type as a variable. Some examples are: Data type Examples Expression 2.54 List {2, 4, 6, 8} Matrix [13 26 93 ] This can be entered as: [1,2,3;3,6,9] Character string “Hello” “xminà10” Function myfunc( arg ) 1.25í6 2p xminà10 2+3i (xì2)ñ 2 à2 {1, 1, 2} “The answer is:” ellipse( x, y, r1, r2 ) Entering multiple statements in a Math Box To enter several statements in a single Math Box, separate them with pairs of colons. Only the result of the last expression is shown. Effects of repositioning or deleting math objects You can delete TI InterActive! math objects (such as Math Boxes, lists, and graphs), and you can drag them to a different position on the page. However, deleting or moving an object can cause results to change in the objects that follow it. That’s because variables persist from one math object to another. The physical positions of the objects determine the order in which they are processed by the TI InterActive! math system. The “math flow” is identical to the reading pattern: left-to-right along each line of a paragraph, and top-to-bottom between paragraphs.

Step 2. Math flow Step 3. If you edit a list or variable at the beginning of the document, the change can ripple throughout the other math objects. Effect of changing 4 to 3 at the beginning of the example. But if you change the value assigned to a variable at the end of the document, the math objects that precede it are unaffected. Effect of changing 4 to 3 at the end of the example. 22 Getting Started with TI InterActive! TII_GettingStarted.doc Getting Started with TI InterActive! Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 22 of 64 Resetting all variables by inserting a math section break At times, the persistence of variables can create a problem. Suppose, for example, that you want to change the expression stored in num for use in a different equation. TIP: Math Section Break is on the Insert menu. Rules for naming variables Inserted math section break shows the resetting effect on the math flow. Variable names that you create: ¦ Can use 1 to 32 characters consisting of letters and digits. This includes Greek letters (but not p), accented letters, and international letters. – Do not use spaces. – The first character cannot be a digit. ¦ Can use either uppercase or lowercase letters. The names AB22, Ab22, aB22, and ab22 all refer to the same variable. ¦ Cannot be the same as a preassigned name. Preassigned names include: – Built-in functions, such as abs( ). For a list of functions, refer to the Functions and Instructions section of the online help. Getting Started with TI InterActive! 23 TII_GettingStarted.doc Getting Started with TI InterActive! Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 23 of 64 Here are some examples: Reusing the last answer Variable name Valid? Myvar Yes My var No. Contains a space. a Yes Log No. Name is preassigned to the log( ) function. Log1 Yes 3rdTotal No. Starts with a digit. TI InterActive! automatically stores the last calculated result as a system variable named ans. You can use ans in the next Math Box to create a chain of calculations. For example, calculate the area of a garden plot that is 1.7 meters by 4.2 meters. Then calculate the yield per square meter if the plot produces a total of 147 tomatoes. 1. In a new Math Box, type 1.7*4.2, and press Enter on the computer keyboard. 2. Type 147àans, and press Enter on the computer keyboard to find the yield. 24 Getting Started with TI InterActive!

There are two ways to resize an object. ¦ To resize an object that has been saved to the document, select the object with a right mouse click, select Format from the right-click menu, and change the resize settings as desired. ¦ Select the object and drag the resize handles to an appropriate size. Resize handles are the small squares located on the selection outline. In the example below, the diagonal arrow cursor next to the 6 indicates that the list object can be resized by dragging the mouse. Resize handle Moving objects TIP: Use View 8 Nonprinting Characters, which displays line breaks as , to view the lines in a document. Deleting objects Resize cursor To move an object, point to the object with your mouse and drag it to the new location. If the object does not drop at the location you want, it may be because there isn’t an empty space or sufficient room. Since objects are inserted into the document as characters, there must be an empty space with sufficient room in which to place the object. “Empty spaces” are found next to existing objects or text and on empty lines. Sometimes it may appear that there is an empty line at the end of the document when there is not. There are two ways to delete objects that have been inserted in a TI InterActive! document. ¦ Point to the object using the mouse and single click. Then press the Delete key on the computer keyboard. ¦ For objects that have been inserted as inline-with-text objects (see next page), position the cursor to the right of the object and press the Backspace key on the computer keyboard.

Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 53 of 64 Using floating objects The default for TI InterActive! is to create objects as inline-with-text objects. To place objects precisely in the document, convert them to floating objects. TIP: The Edit 8 Object menu is also available via a right-mouse-click on the object. To convert objects to floating objects, select the object and then select one of the Edit 8 Object menu items. ¦ Inline with text Causes the object to float in line with the text. ¦ Floating with text around Causes the object to float on the page with text or other inline objects flowing around it. ¦ Floating with text top & bottom Causes the object to float on the page with text or another inline object above and below it. Inline with text Floating with text around Floating with text top & bottom To move a floating object, drag the object with the mouse to the desired location. For additional control, select the object and use the arrow keys on the computer keyboard to position the object on the page. If two or more objects are floating objects, they can be placed adjacent to each other or overlapping. Once an object is changed to floating and placed in the document, it does not change its position unless you move it. 54 Getting Started with TI InterActive! TII_GettingStarted.doc Getting Started with TI InterActive! Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 54 of 64 Math updates The TI InterActive! math system is dynamic and performs updates of all variables whenever a new object is defined, modified, or moved. This feature enables new ways in which to illustrate ideas and concepts. It may also require some experience in order to know what to expect. Each object has an evaluation point that determines when its information is available for evaluation by the math system. Evaluations occur in a specific order. ¦ Objects whose evaluation point appears above or to the left of other objects’ evaluation points are evaluated first. ¦ Subsequent objects are evaluated in this spatial order until all objects in the document are evaluated. This evaluation occurs many times during the course of creating or editing a document. The example below illustrates the importance of the math evaluation order. Document 1 Document 2 In Document 1, a is defined as 20 and 30 in consecutive Math Boxes on the same line. In Document 2, the definition order is reversed, and a is defined as 30 and 20, again in consecutive Math Boxes on the same line. The position of the second Math Box is significant to the evaluation of the third Math Box, which contains the expression factor(a). In the first document, a is equal to 30 when the third Math Box is evaluated. In the second document, a is equal to 20 when the third Math Box is evaluated.

Karen Davis Revised: 8/22/03 12:20 PM Printed: 8/25/03 8:04 AM Page 55 of 64 An additional aspect of math updates is the location of the evaluation points for each object. For all objects (except the Math Box, graph, and matrix), the evaluation point is located at the topleft corner of the object. For the Math Box, graph, and matrix, the evaluation point is located at the bottom-right corner. To view the evaluation points in a document, select the View 8 Nonprinting Characters menu option. A small dot displayed on the object indicates its evaluation point. Setting preferences It is important to review the default preferences when you first install TI InterActive!

For purposes of this Agreement, a site (“Site”) consists of one entire physical campus of an educational institution accredited by an association recognized by the U.S. Department of Education or the State Board of Education, or by their equivalents in other countries. All additional terms of the Agreement apply regardless of the type of license granted. SINGLE-USER LICENSE EDUCATIONAL MULTIPLE-USER LICENSE EDUCATIONAL SITE LICENSE If you paid a license fee for a Single User License, Licensor grants to you a personal, non-exclusive, nontransferable license to install and use the Program on a single computer.

You may make one copy of the software for backup and archival purposes. You agree to reproduce all copyright and proprietary notices shown in the software and on the media. Except as expressly stated herein or in the documentation, you may not duplicate such documentation. In cases where TI supplies the related documentation electronically you may print the same number of copies of the documentation as the number of computers specified for the license fee you paid. All the computers on which the Program is used must be located at a single Site. Each member of the institution faculty may also use a copy of the Program on an additional computer for the sole purpose of preparing course materials. If you paid a license fee for an Educational Site License, Licensor grants you a non-exclusive, nontransferable license to install and use the Program on all institution owned, leased or rented computers located at the Site for which the Program is licensed.

IN JURISDICTIONS WHICH ALLOW TEXAS INSTRUMENTS TO LIMIT ITS LIABILITY, TI’S LIABILITY IS LIMITED TO THE APPLICABLE LICENSE FEE PAID BY YOU.
