 Feb18 comment $\int_{0}^{2} (2x - x^2)^n dx$ recurrence relation I still don't see how Feb18 comment $\int_{0}^{2} (2x - x^2)^n dx$ recurrence relation How do you get to the second row? How is $-2n \int_o^2 (...) dx$ equal to that?

This uses derivatives and right now we're using the limit definition to computer derivatives and not actually deriving functions, so I can't use this.
