Suppose thatf : [0, 1]--->R is continuously differentiable.
(a) Show that there is some number M such that |f'(x)|< M for all x.
I understand mean value therorem but use it to solve this problem. Can you give me some hints please?
Thanks

From lecture notes: By the boundedness principle, a continuous function on a closed interval attains its maximum and minimum.
Therefore there exists a number M such that f(x)<=M for all x belong to [0,1]. How do i apply this to
I think i have to do something like.... how do i complete the answer? thanks
