title: trouble rendering equations on wordpress.com
body: <p>I tried to incorporate some equations into a wordpress blog entry.  No special installation, just using the version of mathjax Wordpress comes with.</p>
  
  <p>My paragraph reads </p>
  
  <blockquote>
    <p>This action is invariant under conformal symmetries of the worldsheet
    $latex  z \to z + \sum_{n = -\infty}^\infty  \epsilon_n z^{n+1}  $ , where $latex z$ 
    parameterizes the worldsheet.  In 2 dimensions, the conformal group is especially large and > there are infinitely many generators $latex  \l_n: z \to z +  \epsilon_n z^{n+1} $ .</p>
  </blockquote>
  
  <p>Both equations give a "formula does not parse".  Only the "z" renders correctly.  If I put this into a latex document, the formula compile.  Can you explain?</p>
  
  <p>The <a href="http://wordpress.org/extend/plugins/wp-latex/faq/" rel="nofollow">FAQ</a> page gives hints, but does not resolve my problem.  The hints on the page do work.</p>
