Introduction to LATEX
Introduction

LATEX is. . .
. . . a sophisticated document preparation sytem.
LATEX has. . .
Stylistic uniformity
Bibliography support
Sophisticated structuring abilities
Reference tracking
Highly extendible capabilities

Introduction to LATEX
Introduction

LATEX is not. . .

. . . a word processor.
LATEX does not. . .
Spell-check your documents1
Give you complete control over formatting
Provide a graphical interface for editing
“You take care of writing, and we’ll take care of presentation.”

1

You can use ispell to check your LATEX

Introduction to LATEX
Introduction

Why LATEX?
Presentation shouldn’t get in the way of content.
For example. . .
With a word processor, you spend valuable time agonizing over
what font size to make the section headings.
With LATEX, you just tell it to start a new section.
With a word processor, changing the formatting means you have to
change each instance individually.
With LATEX, you just redefine the relevant commands.
With a word processor, you have to carefully match any provided
templates.
With LATEX, you can be sure you’ve fit the template, and switch
templates easily.

Introduction to LATEX
A Basic Document

”Hello LATEX!”
Creating a LATEX Document
Write a .tex file using any text editor and save it in the
MiniPaper folder
% this is hello.tex
\documentclass{article}
\begin{document}
Hello, \LaTeX!
\end{document}

Compile using the RSI Makefile
$ cd ∼/RSI/MiniPaper/
$ make hello.pdf

Preview the results
$ evince hello.pdf &

Writing LaTeX Code

documentclass
LATEX has several templates, selected using \documentclass
Classes:
book
report
article
letter
beamer
Etc.
You’ll be using the ‘article’ class for your paper, ‘beamer’ class for
your presentation

Introduction to LATEX
A Basic Document
Writing LaTeX Code

Declarations and Environments
Declarations. . .
Are stated once
Take effect until further notice
Can optionally be constrained
Ex. \documentclass, \small
Environments. . .
Have matching begin and end declarations
Must be constrained
Ex. \begin{document} ...\end{document}

Introduction to LATEX

Writing LaTeX Code

Arguments
Required arguments. . .
Are contained in curly braces
Must be included
Ex. \documentclass{article}
Optional arguments. . .
Are contained in square brackets
Can be left out
Give you more control over the commands
Ex. \documentclass[12pt]{article}

Introduction to LATEX

Writing LaTeX Code

Special Characters

Another type of command
Don’t define any formatting or structure
Print non-standard characters or characters which usually
mean something else
Ex. \LaTeX, \textbackslash, \%
Note: % is a special character reserved for comments (after a %,
the rest of a line is ignored by the compiler)

Introduction to LATEX

Packages

Packages allow you to further customize LATEX.
The command:
\usepackage{name}
Some packages:
graphicx, epsfig, geometry, fancyhdr, setspace, amsmath, listings,
xcolor, url. . .
Most of the packages you’ll need are already included in the
template

Introduction to LATEX

Basic Formatting

Font Types
Font face:
\emph{Text}, \textbf{Text}, \texttt{Text}, \textrm{Text},
\textsf{Text}, \textsc{Text}
Font size:
{\tiny Text}, {\scriptsize Text}, {\footnotesize Text},
{\small Text}, {\normalsize Text}, {\large Text}, {\Large

Text}, {\LARGE Text}, {\huge Text}, {\Huge
Alignment:

Basic Formatting

Spacing
Margins
The default: between 1.5 inches and 1.875 inches
Setting margins: \usepackage[margin=0.5in]{geometry}

Paragraphs and other breaks
Paragraphs are separated by a blank line.
You can force a new line using \\
To force a new page, use \newpage or \clearpage

Other spacing
Force a space using ∼
Add space using \hspace{1in} or \vspace{1in}
Fill space using \hfill or \vfill

LATEX and You
The Files

The RSI File Structure
In your MiniPaper or Paper directory, you’ll notice several files. . .
main.tex brings everything together, don’t edit it
preamble.tex contains any additional packages or macros
cover.tex contains the cover information (title, author, etc.)
abstract.tex and summary.tex contain the text of your
scientific abstract and executive summary, respectively
paper.tex contains the main body of your paper, including
any and all figures, tables, etc.
biblio.bib is a BibTEX file containing your references
appa.tex contains the text of any appendices you may have
Compile using make main.pdf

Introduction to LATEX
LATEX and You
The Files

The Title Page
cover.tex is where you define the content of your title page
It includes declarations of the title, author, and date
You should replace the title and author as needed, but leave
the date alone
\title{Length-enhanced superlative verbiage}
\author{Joe Everystudent
\vspace{0.5in}\\
under the direction of\\
Dr. Famous Person\\
Massachusetts Institute of Technology
\vspace{1in}}

The title page is created automatically using the maketitle
command in main.tex

Introduction to LATEX

The Files

Abstract and Summary
The minipaper only has an abstract
Your final paper will have both a technical abstract and a
non-technical summary
All you need to do is fill in the text, and the template takes
care of the rest
Behind the Scenes
\begin{abstract}
\input{abstract}
\vspace{1in}
\begin{center}\textbf{Summary}\end{center}
\input{summary}
\end{abstract}

Bibliography
biblio.bib acts as a database of references, and only includes in
the bibliography those references you cite in your paper
BibTEX
@article{nameofentry,
author = {John Backus},
title = {Symmetric Encryption},
journal = {Journal of Modalities},
volume = 46,
year = 1993,
number = 2,
pages = {44--57}
}

So, why LATEX?

LATEX allows you to worry about the content and the
structure, rather than the presentation.
LATEX has one of the most advanced math typesetting systems
around.
LATEX is incredibly extendible.
LATEX keeps track of references so you don’t have to.
LATEX allows you to make more consistent, and more easily
changeable, documents.
