I wish an easy way to communicate mathematical equations with gmail.
There\'s a javascript script called AsciiMath, which should translate Tex-like equations into standa
What about using texify and converting it just to a html image or a link to that image? This would save some work with parsing and converting the tex math code and wold work fine even with simple mail clients.
Depending on whom you communicate with the easiest solution is sometimes to email raw tex.
As far as I can figure out, GmailTeX (suggested in the top answer) does not work in Firefox anymore.
I can suggest the browser plugin MathQuill for Gmail (also exists for Chrome), which allows to edit formulas within the Gmail compose window, and converts them into pictures. (Like GmailTeX in concept, but with an interactive editor.)
Disclaimer: I am the author of the plugin.
GmailTeX does exactly what you want. It is pure javascript so it works in Firefox, Chrome, Opera.
