MathJax Filter for Moodle

This filter replaces the need for the latex filter in Moodle. It has a better display and supports more input types. It also has the added benefit of being completely client-side, not requiring any server side LaTeX rendering. It uses the fantastic MathJax library.

This filter renders any LaTeX within Moodle that is surrounded by special delimiters using the MathJax library. There are currently two types of LaTeX that can be rendered:

• Block
  Delimiters: $$ and $$
  Example: $$ \sqrt{123} $$
  
  
• Inline
  Delimiters: \( and \)
  Example: \( \sqrt{123} \)
