Yeah, I know that. I even understand the proofs behind the elementary differentiation formulas. It's just that, when I initially looked at this problem, I was confused because of the notation used. We were studying the derivatives of inverse functions at the time, and then my techer threw this gem in there. Threw me for a loop.
