For questions about the formulation of a proof. This tag should not be the only tag for a question and should not be used to ask for a proof of a statement.
Questions with this tag are about the presentation of a mathematical proof. Questions might include:
- Should I include [x-mathematical detail] at [y-part of this proof]?
- Is the following a sufficient proof of [x-mathematical tidbit]?
But this tag is not for asking someone else to write a proof for you, or for how to answer some question. Questions such as: My professor asked me to prove the Pythagorean theorem and I don't know how to begin are not to have this tag.
This tag is intended for use along with other, more "mathematical" tags. A question about the writing of a proof in abstract algebra, for example, should have abstract-algebra as well.
