Frequently, I see users--often users with some $>1$ amount of reputation--who, while using MathJax, have some fairly annoying flaws: for example, $pi$ instead of $\pi$ or improper use of curly braces (e.g. $A_(1)$ instead of $A_{(1)}$). Most often these are just annoying but sometimes they can be genuinely ambiguous or even nonsensical.
I have certainly seen many commenters direct newer users to the MathJax tutorial. However, I have very rarely seen commenters suggest MathJax tips to users with poor MathJax skills with the goal of improving the OP's formatting for future questions.
Is making such suggestions considered proper and worthwhile? Is there a reason this isn't done more? If such suggestions are considered proper, are all such suggestions considered worthwhile: should nitpicky details like $cos x$ instead of $\cos x$ be brought up or just errors that actually effect understandability?
\ln, \log, \gcd, \operatorname{Funky}(x)
etc. $\endgroup$\cos x
rather thancos x
is that MathJax will be able to generate the proper output for screen readers and other assistive technology (\cos x
can be read as "cosine x", whilecos x
is read as four separate letters, "c-o-s-x"). $\endgroup$
