I was doing some cleaning up in equation formatting etc. and wondered if there was a style guide somewhere. I had the following specific questions but if there isn't already a style guide I would be happy to start one and compile some of items in the forum as well.
What is the capitalization style for headings (H1, H2, and H3)?
When should italics be used versus invoking LaTeX for variables?
When should a superscript be used for a unit on the bottom of a fraction and when should a / be used?
When should items be capitalized in tables?
When should figures have a Figure label with a number?
