# Thread: Using Tex in the math help forum

1. ## Using Tex in the math help forum

Hi all. I appologize as I am sure this has already been asked. I am new to the math help forum but I am fluent in LaTex. How do compile code so that it displays in my posts?

Any and all help is appreciated.

Here is an example:
$$\sum\limits_{k = 1}^\infty {\frac{{\cos \left( {\pi k} \right)}}{{k^2 }}}$$ gives $\displaystyle \sum\limits_{k = 1}^\infty {\frac{{\cos \left( {\pi k} \right)}}{{k^2 }}}$

The $\displaystyle \Sigma$ on the toolbar is a shortcut to  brackets.
