Mathematical Equations - Help Needed

I am using the FCKEditor to let my users create rich HTML content. I have embedded this FCKEditor in my form so that I get the out put and can store it in the database.

But how do I allow creation of mathematical equations in such a case since FCKEditor does not support them? Is there any other software/script that support equations?

Thanks in advance.

 

try searching for Latex

 

Thanks. Any recommended one implementing Latex? Found a few but how do I integrate them into a form?
