Question: Every once in a while I miss having the option to write some LaTeX math on SO. E.g. when [talking about automata](https://stackoverflow.com/questions/885411/how-do-i-build-this-finite-automaton). I'm certainly [not the only one](https://stackoverflow.com/questions/1106929/find-all-combinations-of-coins-when-given-some-dollar-value/1106968#1106968). And I think the person answering [this question](https://stackoverflow.com/questions/1055098/how-do-i-design-the-transition-functions-for-this-pushdown-automaton) would have appreciated it as well. I'm sure there are more examples.

It can be done, look e.g. at the [Physics forums](http://www.physicsforums.com/showthread.php?t=8997). Multiple solutions exits, either by converting the LaTeX code to an image or MathML.

Since the fields of theoretical computer science and computer programming overlap (formal languages, data structures, ...), and because plenty of users are acquainted with LaTeX, I think it makes sense to provide support for mathematical notation on SO. What do you think?

Answer: 
This is implemented on <http://math.stackexchange.com> -- you can check it out there. It will never be on Stack Overflow, though, as it is an extremely heavy dependency.

[TeX math markup is sorely needed](https://math.meta.stackexchange.com/questions/2/tex-math-markup-is-sorely-needed)
<http://mathbin.heroku.com> works kind of like a code paste bin for math equations. It has an embed option, but it doesn't work with SO because it uses a `script` tag. It's a quick work around as you don't have to URL encode the LaTeX string. You also have to include the LaTeX string as part of your post in case someone decides to edit it and hit save.
