WebTheorem: Let $f$ be a continuous real-valued function defined on a closed interval $ [a, b]$. Let $F$ be the function defined, for all $x$ in $ [a, b]$, by $$F (x) = \int_a^x\!f (t)\, dt.$$ Then, $F$ is continuous on $ [a, b]$, differentiable on the open interval (a, b), and $$F' (x) = f (x)\,$$ for all $x$ in $ (a, b)$.
