To workaroud the problem, please use html package provided by 
latex2html and use \latexhtml command:

  \usepackage{html}
  ...
  \section{\latexhtml{$\sin x$}{sin x}}
  % or \section{\latexhtml{$\sin x$}{\HTMLcode{I}{sin x}}}
  ...
  \section{\latexhtml{$x^n$}{x\HTMLcode{SUP}{n}}}
  % or \section{\latexhtml{$x^n$}{\HTMLcode{I}{x\HTMLcode{SUP}{n}}}}
