Chapter 4 Numerical Integration In this chapter, we consider approximating integrals of function one, two, or three variables. Numerical integration formulas, or quadrature formula, are methods for the approximate evaluation of definite integrals. They are needed for the compu-tation of those integrals for which either the antiderivative of the integrand cannot be expressed in terms of elementary functions or for which the integrand is available only at discrete points, for example from experimental data. In addition and even more important,quadrature formula provide a basic and important tool for the nume-rical solution of differential and integral equations.
