Latex2html, tex4h and MathJax example on small bit of math

The latex file is

\documentclass[12pt]{article}
\usepackage{html}
\usepackage{color}
\pagecolor{white}
\usepackage{amsmath}
\begin{document}

 \begin{align*}
  v^{2}   &  =\left(  \dot{x}+v_{x}\right)  ^{2}+v_{y}^{2}\\
          &  =\dot{x}^{2}+l^{2}\dot{\theta}^{2}+2\dot{x}l\dot{\theta}\cos\theta
  \end{align*}

\end{document}

Results

1. latex2html foo.tex
2. htlatex foo.tex "html"
3. Mathematica HTML output
4. MathJax produces (renders directly in browser, assuming your browser supports it then you'll see the math below). \[ \begin{align*} v^{2} & =\left( \dot{x}+v_{x}\right) ^{2}+v_{y}^{2}\\ & =\dot{x}^{2}+l^{2}\dot{\theta}^{2}+2\dot{x}l\dot{\theta}\cos\theta \end{align*} \]
