Instructions on how to use LaTeX on CrossValidated

Question

Questions formatted in LaTeX are easier to read, but not everyone who has permission to review a question/answer knows how to do it (maybe I am an "outlier" here, but not sure).

Are there any instructions on CV about how do it?
Like when you post a commentary and it appears _ _ for italic, and etc.

Reflection: There are many ways to learn how do it, for example, clicking on "edit" button on a LaTeX formatted question to see how is done, or just looking on internet.
Nevertheless, I think if CV provided information on this topic, more users would feel encouraged to help on this task.

Answer 1

Here are some options that I know of:

• There is a CV help page for the markdown options that the site supports. That covers things like italics, and some (but very little) actual $\LaTeX$.
• There is a comprehensive 'tutorial' thread on meta.Mathematics here: MathJax basic tutorial and quick reference.
• One way to learn is to find something that uses $\LaTeX$ that you would like to also be able to do and right-click on it. Then select Show Math As -> TeX Commands, and it will display the code that was used to create it.
• If you need to identify the $\LaTeX$ name / code for a symbol and you can draw it, detexify might help.
• Stack Exchange does have a Q&A site dedicated to TeX; that might be helpful as well.
• After that, it's the broader internet; I've found this MathJax documentation site to be very comprehensive and informative, but it's really slow to load. This webpage discovered by @Andre is less extensive, but loads much faster. There's a handy 'reference card' here.
• Lastly, I suppose you could ask a question about how to do something specific here (e.g.: latex-macros-for-expectation-variance-and-covariance).

Answer 2

Probably the easiest option is offered in the Operations Research site's MathJax FAQ:

How do I use MathJax on this site?

That answer lists three tools, the last one, MathPix, will convert a PDF to MathJax. After conversion little or no editing is required.

OR's FAQ isn't as huge as the one at Math.SE, but it is probably closer to statistics than the ones offered at Quantum Computing or other sites. If CV creates their own MathJax FAQ (which they should) they can provide links to the other sites MathJax FAQs at the end of the answer.
