Sorry, guys, this isn't abstract but the calc board didn't seem very active... I could really use the help on this one...

Prove:
f(x): [a, b] ----> R has f'(x) continuous @ each x in [a,b] then the definite integral from a to b exists

Could someone please make a proof for this one? I am lost as to what to do.

f is diffible, so f is continuous, hence (Riemann) integrable.
