This chapter presents Newton鈥揅otes quadrature formulas for approximating integrals by performing polynomial interpolation and integrating the polynomial exactly. In particular we discuss the midpoint, trapezoid, and Simpson's rules for numerical quadrature. The composite forms of these rules are shown ...
