f'(x) = 2x(f(x)) and f(2) = 5, find...... 1. The problem statement, all variables and given/known data Suppose that f'(x) = (2x)(f(x)) and f(2) = 5 Find g'(∏/3) if g(x) = f(secx) 2. Relevant equations no idea 3. The attempt at a solution No idea where to begin but i'll give it a try... nothing comes to mind...i don't know where to start... before I attempt to solve, can anyone explain what this question even means? or point me in the direction to some online source that explains this...I would greatly appreciate it. I never had a problem where there was a function of the form f(x) within a derivative function statement.
