8. Applications: Net Change Theorem

9. Differentiation and Integration: Inverse processes The Fundamental Theorem of Calculus If f is continuous on [a, b], then 1. : If f is integrated and then is differentiated, we arrive back to f. 2. : If we take a function F, first differentiate it then integrate it, we arrive back to F, but in the form of F(b) – F(a).
