I've wanted to include math with webpages for a long time. Wouldn't it be great if you could include an equation on a webpage, and have it rendered like in LaTeX?
It looks like MathJax does this.
\[ \cos \theta = \frac{1}{2} e^{j \theta} + \frac{1}{2} e^{-j \theta} \]I am not affiliated with the mathjax project in any way.
