1. The problem statement, all variables and given/known data Let F(x) = integral from x to 1 ( [tex]3t^3 - x^2 t ) dt[/tex] 1. Calculate F'(x) 3. The attempt at a solution I know the answer is x^3 + x. However, I am not sure how it is obtained. I know about implicit differentian, but I have never done implicit integration. How can you solve the problem?
