## Introduction to %BEGINLATEX{inline="1" color="Lightmaroon"}%\Large\LaTeX%ENDLATEX%

*display* mathematics, it must be surrounded by %\[
and \]%. Thus, %\[\mathcal{N}=\langle \mathbb{N},0,1+,\cdot \rangle \subseteq \langle \mathbb{R},0,1+,\cdot \rangle\]% produces this centered display in the middle of a paragraph, which is preferable for long formulas or ones requiring emphasis.
### Brief Tutorial on %BEGINLATEX{inline="1" color="Lightmaroon"}%\bf\LaTeX%ENDLATEX%

### Document Structure

%BEGINLATEX{inline="1"}%\LaTeX%ENDLATEX% is a complete typesetting language developed by Leslie Lamport on top of Donald Knuth's %BEGINLATEX{inline="1"}%\TeX%ENDLATEX%. Most of it is implemented using LatexModePlugin, but the main use is producing mathematics, since most other formatting is more conveniently accomplished using Wiki constructs. To produce mathematics *in-line*, the %BEGINLATEX{inline="1"}%\LaTeX%ENDLATEX% text must be surrounded by %$
and $%. Thus,

%$\Gamma \vdash Rx_1\cdots x_n$%looks like this in the middle of some text. To

%BEGINLATEX{inline="1"}%\LaTeX%ENDLATEX% is used by most mathematicians, physicists, and engineers for mathematics, and articles and books are typically submitted for publication in %BEGINLATEX{inline="1"}%\LaTeX%ENDLATEX%. There are therefore many helpful web sites, newsgroups, and books about %BEGINLATEX{inline="1"}%\LaTeX%ENDLATEX%. The standard complete reference is Lamport's LaTeX: A Document Preparation System (2nd Edition). The place to start on the web is the %BEGINLATEX{color="Cornflowerblue" inline="1"}%\TeX%ENDLATEX% Users Group.

All %BEGINLATEX{inline="1"}%\TeX%ENDLATEX% codes begin with a backslash (\). Curly braces ({ }) are used to delimit groupings, except in a few cases where optional arguments must be enclosed in square brackets ([ ]). Many symbols have mnemonic names, like `\Alpha`

, `\alpha`

, `\forall`

, `\exists`

, `\lor`

, `\land`

.

A list of some common symbols is given in the LatexSymbols topic. Other off-site lists include: Some Symbols and Some Little-Known Symbols, All the Symbols. Not all the symbols work in the Wiki, but most of them do.

A subscript is indicated with an underline (_). If the subscript consists of more than one symbol, it must be enclosed in braces. Similarly, a superscript is indicated with a caret (^). Thus, %$ \alpha _{ \beta _1^2}^{ \gamma ^{ \delta ^ \epsilon }} $% yields ,

In standard %BEGINLATEX{inline="1"}%\LaTeX%ENDLATEX% 2e documents, the main file has the following structure:

`\documentclass[`*options*]{*class*}

*preamble*

`\begin{document}`

*text*

`\end{document}`

Any text that normally goes in the *preamble* or *text* sections of the
template above can be rendered in TWiki. The *preamble* is typically used
to define new commands, or use LaTeX style-files to extend LaTeX's
functionality. The *text* area contains the actual text to be rendered.
One does not need to use the `\documentclass`

or `document`

environment to
use LaTeX in TWiki.

The ability to render a complete LaTeX document within TWiki, say from an existing file, is currently under consideration. See TWiki:Codev.IncludeExistingLatexDocsInTWiki for details and current status.
