Does there exist a "manual of style" (or "manual of best practices") for LaTeX (especially geared towards mathematical writing)?
For instance, every time I've to write things like
$a^2+b^2=c^2$, where ...
I wonder if I should leave a space between the symbols (i.e., $ a^2 + b^2 = c^2 $), or if I should put the comma inside the math environment (I guess that there is no difference in the output, but I'd prefer to take on good typing habits). Or also, one may wonder if one needs the extra space in this expression:
$$ \int^b_a x^2 \ \mathrm{d}x $$
And so forth. Does there exist a standard reference for this type (and more) of LaTeX-related typographic questions?
