### Maths

Looking around the Internet, I was a little disappointed to find that blogger doesn't natively support Latex. Fortunately there's a nifty program that you can run on a web server that will output latex code as a png.

Let $\dvipng\gammacorrection{1.2}H \leq G$ and $\dvipng\gammacorrection{1.2}x, y \in G$. Then either $\dvipng\gammacorrection{1.2}xH \cap yH = \emptyset$ or $\dvipng\gammacorrection{1.2}xH = yH$.

The two dimentional gradient vector for a function u(x, y) is, $\dvipng\gammacorrection{1.2}\nabla u=\left(\frac{\partial u}{\partial x},\frac{\partial u}{\partial y}\right)$.

All made possible thanks to http://www.forkosh.com/mathtex.html - cheers!
