Formula sheets on exams

Here's a question I just got:

I do have a question that I forgot to ask, Will we be able to use a formula sheet on the exam?

Yes. I'll provide all the basic formulas and numerical constants necessary on the exam itself, and you will be allowed to bring in one sheet of paper of your own containing any information you like. So long as your sheet of paper is 8.5x11 inches ... fair game.

Along those lines: if you find yourself needing a formula or number on a quiz that I have not already provided, just ask, and odds are I will just give it to you.
