I have a problem with the 5 in front of sin! I am trying to get the first derivative of f(x) and I have 3x^2-___cos__x. Is there supposed to be a number? Or am i second guessing myself?

yes, there is.. note that 5 is a constant and it can go out of the integral.. so for that part, it should be -5cos x..
