If you need to put mathematical expressions on a web page and are familiar with LaTeX mark-up, you may want to use MathJax.

In brief: just put the following lines in the <head> section of the web page:
<script src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"></script> Then in the <body>, enclose LaTeX math in \( \) for in-line math or \[ \] for displayed math. Enclosing inline math with $ isn’t enabled by default but can be enabled if you want. To avoid confusing browsers, use spaces around < and > symbols (or use the \lt and \gt macros).

For more information, check out the MathJax site linked above, and in particular http://docs.mathjax.org/en/latest/tex.html.

This should work for any browser that interprets Javascript.
