math test

Lots and lots happening but right now I am working on building a mathematical paremeterization for the strandbeest walking leg. There are a lot of equations so to be able to keep a good copy I want to just write it right into LaTeX here but before I can do that I have to test if the js interpreter will work.

I will be trying to set up mathjax 

\[\begin{aligned} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x - y - xz \\ \dot{z} & = -\beta z + xy \end{aligned} \]

seems to work for me, now to try and remember how to write LaTeX
