More importantly, use your manual to find answers like this, if you don't have it with you then follow the directions to the above FAQ about getting a manual online.

How do I do [some math function or calculation1]?

I'm probably a dick for not answering some of these simple questions, but I won't, because you should get the answer to these questions from:

  1. The TI-82 Manual
  2. Your closest teacher of mathematics

I take this policy because that's what the manual is for, and that's what teachers are for, these are two great resources, and I want more people using them.

However, if these don't resources have the answer (and sometimes they don't), check out these mailing lists. If these folks don't know the answer, nobody does. Anyway, your better off spending your time mailing them, because frankly I hardly ever know the answer.
