1. The problem statement, all variables and given/known data Find the power series of f'(x), given f(x) = x2cos2(x) 2. Relevant equations Correct me if I'm wrong 3. The attempt at a solution Can I just take the derivative of the solution I got previously? If so, what's a good way to write the sequence out so I can easily make a series representation. Or is there a better approach to the problem?
