Let f be a differentiable continuous function on [a, b] and suppose is continuous on [a, b]. Prove - (f2(b) - f2(a)) f (t) (t) dt State any theorems or differentiation rules used in your proof. Hint: let F (x) Let f be a differentiable continuous function on [a, b] and suppose is continuous on [a, b].
