# How to insert TeX code in a Google Document?

I see that you can insert equations, but I would love to have the freedom of TeX, all mathematics symbols.

Is there any way to insert e.g. $$\int_{0}^{\infty}$$ and it parses it?

No, Google Documents do not contain a LaTeX parser. There is a limited support for TeX macros, mostly for characters: you can type \int followed by a space and get the integral sign; then type ^ and get superscript, etc. To use the full power of LaTeX, you need a LaTeX processor, which Google Docs is not.
