Sorry, that's my bad, part of my comment got rendered despite using nowiki tags. MathJax is the math formula environment you get using \ ( and \ ) in place of $$ and $$ (there shouldn't be spaces between slashes and brackets, I'm just making sure it doesn't render).

One further nice thing is that you can actually look at the source code of the formula, by rightclicking and selecting Show Math As -> TeX commands.
