Theorem ftc2 22318
Description: The Fundamental Theorem of Calculus, part two. If  F is a function continuous on  [ A ,  B ] and continuously differentiable on  ( A ,  B ), then the integral of the derivative of  F is equal to  F ( B )  -  F ( A ). This is part of Metamath 100 proof #15. (Contributed by Mario Carneiro, 2-Sep-2014.)
