Description
MathTex Equation Edtor is a Free and Open Source WordPress plugin which is able to insert math equations on while adding/editing a post. It can also convert
equations made using the Codecogs editor to be rendered by the MathTex.cgi installation.
This plugin can be used with a mathtex.cgi installation provided at http://www.forkosh.com/mathtex.html or any other service that renders Math LaTeX if supplied
with the markup text on the URL. By default, the latex equations are rendered by the free mathtex.cgi installation provided at http://chart.apis.google.com/chart?cht=tx&chl=.
To run mathTex.cgi installation on your own personal server, installation instructions can be found at http://www.forkosh.com/mathtex.html.
You can also look up my blog post on the step by step installation of mathTex.cgi at http://kobmat.com/math/?p=5805.
For a quickstart guide on how to work with Math LaTeX, you can check on the guide for the syntax at http://www.forkosh.com/mimetextutorial.html
