2.1 Introduction to Quadrature
Definition 2. 1 Suppose that a =I0<1<.<.M=b. A formula of the orm Q月=2,()=0(0+(n)+…+(y) with the property that f(ad r=Qf+ef is called a numerical integration or quadrature formula. The term E() is called the truncation error for integration. The values ak ko are called the uaaratore nodes, an k=0 are ca lled the weights
