<h1><font size="-2">Hypertext Help with LaTeX</font><br><font color="#cc0000">Displaymath</font></h1>

 There  are four environments  that  put LaTeX  in math  mode:  
 <a href="ltx-115.html#math">math</a>,
 displaymath, <a href="ltx-223.html">eqnarray</a>, 
 and <a href="ltx-224.html">equation</a>.  
 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 <strong>not</strong>
 break lines in displaymath or equation environments unless told to do 
 so with a <a href="ltx-181.html"><tt>\\</tt></a> command.   
<p>
 The displaymath environment can be entered by
<pre>
  <tt>\begin{displaymath}
      math equation \\
      second line of math equation
  \end{displaymath}</tt>
</pre>
Because displaymath may be used frequently to display relatively
short equations, there are convenient alternative forms:
<pre>
  <tt>\[ displayed math equation \]</tt>
</pre>
or (the following does not seem to be well documented, but appears to work) 
<pre>
  <tt>$$ dispalyed math equation $$</tt>
</pre>
