MathJax has come a long way since I last looked at it. There is now a CDN hosting the js files, which makes calling it really really easy. It’s being adopted by GiHub for their wiki engine.

Using it with markdown can cause a few bumps, but there seems to be a bunch of ways around this:

- [mathjax in markdown][mim] using some mathjax configuration and custom css
- amazing implimentation in a notetaking app
- php, mathjax and wordpress

Writing a block of %%\LaTeX%% like this

$$ \begin{aligned} \dot{x} & = \sigma(y-x)

\dot{y} & = \rho x - y - xz

\dot{z} & = -\beta z + xy \end{aligned} $$

will render like this

$$
\begin{aligned}
\dot{x} & = \sigma(y-x)

\dot{y} & = \rho x - y - xz

\dot{z} & = -\beta z + xy
\end{aligned}
$$
