Introduction to LaTeX
A Mathematical typesetting system

The Required ElementsAll LaTeX documents must
include the following parts

• \documentclass12ptarticle
• \begindocument
• \enddocument

The PREAMBLE goes here
The BODY of the document goes here
3
Environments

• LaTeX code is set up with environments.
  Everything is enclosed in the document
  environment.
• \begindocument
• \enddocument

The document environment

Environments

• You enter and leave most environments with
  beginning and ending commands of the form
• \beginenvironmentname
• \endenvironmentname

The code/text goes here
5
Some Formatting environments

• \begincenter . . . \endcenter
• Numbered lists
• \beginenumerate
• \item
• \item
• \endenumerate

The first item in the numbered list goes here
The second item in the numbered list goes here
6
More on enumeration

• If you want sub-headings, nest the lists
• \beginenumerate
• \item
• \beginenumerate
• \item
• \item
• \endenumerate
• \item
• \endenumerate

The first item in the sub-list goes here
The second item in the sub-list goes here
7
More on lists

• If you want bulleted lists, you use the same
  format as for numbered lists with
• \beginitemize
• \item
• \beginitemize
• \item
• \item
• \enditemize
• \item
• \enditemize

8
More on lists

• If you want to designate the headings for the
  lists, you use the description environment
• \begindescription
• \itemCase i.
• \itemCase ii.
• \enddescription

The text for Case i. goes here
The text for Case ii. goes here

Typesetting Mathematics

• There are two main math environments
• In-line math mode. This is for equations that
  occur in the same line as narrative. You enter
  and leave in-line math mode with dollar signs.
  Ex f(x)x3-x
• Displayed math. Several entry/exit choices
• \begindisplaymath . . . \enddisplaymath
• . . .
• \ . . . \

Some Miscellaneous Expressions

• Normal text
• How many subsets does
  have?

• LaTeX code
• How many subsets does \emptyset have?

Notice the use of the backslash ( \ ). This is
your message to LaTeX that you are about to give
it a command.

Some Miscellaneous Expressions

• Normal text
• How many subsets does
  have?

• LaTeX code
• How many subsets does \emptyset have?
• A \ 1,2,3,4 \
• A \subseteq B and B \subseteq A.
• f(x)\fracx31x2.
