Thread: Trouble understanding f of... with derivatives and inverses

Things such as f', f^-1, (f^-1)', etc.

I'd like to know the relation between them and how to get from 1 to another. Most of the times I see that the answer is 1 over a certain number. If this is confusing I'll try to find a sample problem.
