As of now, I haven't seen any questions that neccesarily need MathJax formatting, but I'm sure that at some point it'll be needed.
Should we have MathJax support?
Edited to clarify my opinion, feel free to change your vote.
Computer graphics can be very maths-heavy so I think MathJax would be a great addition to this site. I think we should definitely get MathJax, but the community should be aware of the following side effects of activating it:
We've had MathJax for a short while on CodeGolf.SE, and there is at least one bug that may affect Stack Snippets if we get them as well. This is probably not a big deal on this site, but should be kept in mind. The other minor drawback is that posts containing MathJax look pretty messy in the search results, but all the other sites using MathJax seem to be getting along with that as well.
Yes, definitely. While there might not yet be a question that really needs it, once the first matrix and vector computations come in -- and they will definitely come and seem well-fit here (as they did in the previous iteration of that site) -- we'll definitely need it for that stuff to looks reasonably good and not be a pain to write (e.g. by misusing code blocks).
And that's not even everything there is to it. There's other geometric computations, complex rendering integrals, you name it. So yeah, we definitely should have MathJax, and we should have it NAOH!
To back the general requests for MathJax support, the following is a community-editable list for anyone to add examples of questions which along with their answers would benefit from it:
