# I want to use LaTeX, How can I do that?

• LaTeX
I want to write LaTeX. So I write e.g) '\left( \frac a b \right)' . But it looks just back space bar not mathematical equation. Does there need to install TeX program if I want to type LaTeX in Physics Forums???

See the link in my signature below.

Could you kindly give me specific detail?? I can't find proper information about LaTeX in the link you said.

Use itex tag for normal mode and tex tag for display mode.
Write some gibberish in a sentence $E = mc^2$ and then something in display mode
$$\left ( \frac{m}{p} \right ) \in \{-1,0,1\}$$

You could also use double # tag for normal mode like this ##a^2 + b^2 = c^2 ##, but I've been avoiding that since for some reason, it loads longer when I'm reading topics on phone.
