Hypertext Help with LaTeX


There are four environments that put LaTeX in math mode: math, displaymath, eqnarray, and equation. The math environment is for formulas that appear right in the text. The displaymath and equation environments are for formulas that appear on their own line; they differ only insofar as the latter prints an equation number. LaTeX will not break lines in displaymath or equation environments unless told to do so with a \\ command.

The displaymath environment can be entered by

        math equation \\
        second line of math equation

Because displaymath may be used frequently to display relatively short equations, there are convenient alternative forms:

    \[ displayed math equation \]

or (the following does not seem to be well documented, but appears to work)

    $$ dispalyed math equation $$
