Definite integrals

When you were first introduced to integration as the reverse of differentiation, the integrals you dealt with were indefinite integrals. The result of finding an indefinite integral is usually a function plus a constant of integration. In this Section we introduce definite integrals, so called because the result will be a definite answer, usually a number, with no constant of integration. Definite integrals have many applications, for example in finding areas bounded by curves, and finding volumes of solids.
