# How to input using Latex? [duplicate]

I just found this site today and I asked a few questions but I didn't know how to use the latex syntax, so my questions were difficult to understand. Can anyone tell me how to use this Latex program? thanks

• For my purpose, it has up to now been enough to write equations between $...$ or if I want them centered between $$...$$. Most of the usual LaTex commands seem to work between the single or double dollars. – Dilaton Mar 2 '13 at 22:04

The site (and most other stackexchange sites where such is appropriate) use the exact same implementation of MathJax for Latex markup. Basically, just enclose tex within $(inline) or$\$ (set apart equations). Most basic commands work, like \frac and \sin.
