1. Introduction This is a concise summary of recommended features in LATEX and a
couple of extension packages for writing math formulas. Readers needing greater depth
of detail are referred to the sources listed in the bibliography, especially [Lamport], [LUG],
[AMUG], [LFG], [LGG], and [LC]. A certain amount of familiarity with standard LATEX
terminology is assumed; if your memory needs refreshing on the LATEX meaning of command,
optional argument, environment, package, and so forth, see [Lamport].
The features described here are available to you if you use LATEX with two extension
packages published by the American Mathematical Society: amssymb and amsmath. Thus,
the source file for this document begins with
\documentclass{article}
\usepackage{amssymb,amsmath}
The amssymb package might be omissible for documents whose math symbol usage is rela
tively modest; the easiest way to test this is to leave out the amssymb reference and see if
any math symbols in the document produce `Undefined control sequence' messages.
Many noteworthy features found in other packages are not covered here; see Section 10.
