How to use TeX or LaTeX commands in this forum?

[X]

Many a time, when I have to ask or answer in this forum(specially math question),I can't express it efficiently, because this forum does not support TeX commands(or at least I don't know how to make this support).

If anyone know how this forum uses TeX or MathJaX, please let me know.It will be helpful to me and others as well.

Thanks.

I understand your concern. There is one possibility: Use the following link to type in Latex what you want to ask, save the output as image or pdf and then post it here:
