**This is an old revision of the document!**

TeX is a powerful typesetting system that is the current standard for creating mathematical documents. A system called LaTeX, which includes TeX along with many “macros” to make your life easier, is used by most mathematicians and many professionals in other scientific fields.

The LaTeX Wikibook is an excellent, readable reference on LaTeX fundamentals. It also includes a quick, easy intro to the `beamer`

document class, which is used for slide presentations.

Decide whether you're going to use the department computers (Linux) or your own (Windows, Mac, or Linux). Getting LaTeX working on your computer takes two steps: (1) installing LaTeX, and (2) getting an editor. Once you've completed these two steps, download an example TeX file (see below) and try compiling the TeX file into a PDF. Congratulations, you are now a LaTeX user!

– Insert link to a basic TeX file template here –

Install MacTeX, which includes TeXShop. Open a LaTeX file in TeXShop and click the “Typeset” button. You can make changes in the editing window and view the results in the PDF preview window.

Install proTeXt.

Using a terminal, change into the directory where your LaTeX file is. If your file is called `myfile.tex`

, then run the command `pdflatex myfile.tex`

. In the same directory should be `myfile.pdf`

. You can make changes using any text editor (or retransfer / download your updated LaTeX file) and rerun `pdflatex`

.

If you get a `command doesn't exist`

error, some of the “local machines” (like the math department computers in the grab lab) don't have TeX/LaTeX installed. First, SSH into one point/round/line/tangent, cd to the right directory, and try again. If you're running Linux on your own computer at home, you might need to first install tetex.

An error message indicates invalid LaTeX. When you get a message like,

! LaTeX Error: Bad math environment delimiter. See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. l.12 \begin{displaymath} ?

enter either `q`

or `x`

to get out. LaTeX suggests the error is at line 12. In reality, it may be on some line nearby.

There are many programs available for editing TeX files. Here are a few:

- Overleaf – real-time collaborative writing and publishing tools
- Sublime Text – general code editor, has good packages for TeX editing
- Add your favorite editor here!

Everything before the command `\begin{document}`

is called the *preamble*. You may have noticed that some LaTeX preambles contain lines starting with `\usepackage`

. This is how you load packages, which contain even more macros that work on top of the basic LaTeX setup. For example, the `diagrams`

package enables simple commands to create commutative diagrams.

Some of these packages may already be installed in your version of TeX.

Package | Description |
---|---|

mathtools | Don't fly without it. Includes the `amsmath` package while adding bug fixes, useful settings, more symbols, and new environments. |

amssymb | Adds math symbols. |

mathrsfs | More math symbols. |

geometry | Used to easily control page size and page margins. |

parskip | Replaces paragraph indentation by vertical whitespace between paragraphs. |

color, xcolor | Add text coloring commands. |

hyperref | Adds commands to create internal and external hyperlinks in your documents, including page links in a table of contents. |

setspace | Use this to create one-and-a-half spacing, double-spacing, etc. |

diagrams.sty | This is Paul Taylor's commutative diagrams package. |

- LaTeX Mathematical Symbols – includes all the common mathematical symbols
- Comprehensive LaTeX Symbol List – for all the other symbols
- TeX/LaTeX Stack Exchange – when you're lazy or desperate, ask the LaTeX community for help
- The TeX Users' Group (TUG) is a good place to look for all things (La)TeX. In particular, TUG maintains the Comprehensive TeX Archive Network (CTAN), which contains many files for learning about and extending the capabilities of LaTeX.
- Another popular book is George Gratzer's
*Math into LaTeX*, the first part of which is available online. (This file contains a comprehensive introduction for getting started with LaTeX as well as well-formatted tables of special characters.) - A popular reference, especially for those just starting to use LaTeX, is the (Not so) Short guide to Latex. It has pages of sample math codes and tables of math symbols including arrows, binary relations, and more.
