I'm in the toughest school in my province and in enriched math course. We are learning derivatives and doing some hardcored stuff. Does anyone know any websites that have tons of good practices for derivatives?
Thanks a lot in advance!

Here is a problem:
Prove: $(fg)^{(n)}(x_0) = \sum{ {n \choose k} f^{(k)}(x_0)g^{(n-k)}(x_0)}$, $k$ runs from $0$ to $n$ in the sum.
provided $f$ and $g$ have $n$ derivatives at $x_0$.
