Wysiwyg for math equations

Question

I have a website for non-professional math users. I am looking for a WYSIWYG for math equations. I have found wiris but it isn't free.

What I need:

• Simple, without programming knowledge (like MathML).
• Similar to WolframAlpha equation input or the Wiris one.
• Real-time convertion to visual equations.
• Option to store the input in Latex.
• I have removed the Javascript restriction and I could accept any kind of webplugin that follow the previous bullets. (HTML5, java, Jquery etc)

Answer 1

You could use MathJax. It's a free, opensource, purely Javascript library for rendering math equations. Stack Exchange uses it (that's how I heard of it). It supports input through LaTeX and MathML according to it's site (I've only used the LaTeX input). It looks like it has everything you want.

Answer 2

You can try MathQuill ^[1], which isn't really a WYSIWYG editor but you can call it like a markdown editor, so say we use * to make the text italic like

*This will be italic on Stackoverflow*

Same way using MathQuill, say you want to make a fraction, of 3/4 so you can write it as

\frac and than type out the numbers, and switch the caret using arrow keys or say you want square root of x so you need to write

\square and than the x

You can also take a look at FMatch but personally I feel that will be a bit loaded, but you can give a shot

Answer 3

TeXmacs is a very good editor suited for editing texts with mathematical formulas.

TeXmacs has import and export to LaTeX, but after exporting to LaTeX you need afterward to edit the LaTeX file manually, to insert all necessary macroses there.

I have written a book in TeXmacs (however it is somehow too slow for texts above 200 pages).
