Here is a good starting point to learn how to use LaTeX on PHF. Wrap the tags [ math ] ... [ /math ] around your code.
For example, the code
[noparse]\(\displaystyle \frac{1}{\sqrt{1  \frac{v^2}{c^2}}}\)[/noparse]
produces
\(\displaystyle \frac{1}{\sqrt{1  \frac{v^2}{c^2}}}\)
And note that you can left click on the script and a new box will pop up, giving you the code.
