Moral based question:

[Daseal]

I also don't consider it cheating, because I've done the work to learn how to use the formulas. I think being forced to memorize them is quite silly. What does forcing a student to memorize a formula really prove?

When it comes down to one thing -- it's if it would be considered cheating. I've heard examples from others. If the professor had said you can't program equations into your calc -- this would be a non-discussion, IMO. That's cheating. This is grey area, which ethics is all about.
