But that is NOT what I wrote. Read it properly! 5. ## Re: prove that differentiation and integration are inverse functions?? how can $\left( {b - a} \right)f'(c) = F'(b) - F'(a){\rm{where}}F'(x) = f(x)$ implies $\[\left( {b - a} \right)f(c){\rm{ }} = F(b) - F(a){\rm{where}}F'(x) = f(x)$$

sorry but i cant get this step ...........
