# Can I use amsmath in notebook?

I'd like to use Sage Notebook for typing my LaTeX papers. I'd like to be able to use environments such as `theorem`

`proof`

etc. Is this possible via Sage Notebook? Can I use a custom preamble such as: `\usepackage{amsmath, amsthm, amssymb}`

?

I think with the upcoming (momentarily) upgrade to using MathJax in the notebook this will be possible from the server side. I don't know if the client (you) can do that with a simple switch if that isn't turned on already.
