I'm using a method which allows you to use Mathjax inside of Anki. I'm not sure where the instructions are, but it involves creating custom note types with extra code that loads Mathjax.
The good news is that the new Anki 2.1 which just came out has built-in Mathjax support, so if you're using that, you can just start using Mathjax. Note that the default Mathjax code is not $ and $$, but this is configurable (though if I were starting from scratch I'd probably just use the default).
