What information should I include in a question about homework?
The following are some things that may help your question get better answers, or at least answer more tailored to your situation.
The context. What kind of course it is, what textbook you use. It wouldn't help you if someone gives an answer using some sophisticated, high-powered machinery that you have never seen before. (An example would be asking for help about a step that is used to prove a big theorem in the textbook, and receiving an answer using said big theorem.)
