Over on Worldbuilding Stack Exchange there is How do I add mathematical notation using Latex MathJax?
This gives some useful pointers on the kinds of things that are commonly required when writing questions and answers there, and links to a much more comprehensive guide on Mathematics Stack Exchange.
Could we benefit from a similar guide on our meta site, focusing on things most relevant to computer graphics (matrix notation, Greek letters)?
\smallbut I had to look up how to do this on the Worldbuilding post, so I wondered if we could use one here that people can easily find/link to. $\endgroup$
