Abstract

In this chapter we discuss numerical approximation of the integral 5.1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\begin{array}{rcl} I(f) ={ \int \nolimits \nolimits }_{{\mathbb{S}}^{2}}f(\eta )\,d{S}^{2}(\eta ).& &\end{array}$$ \end{document}The integrand fcan be well-behaved or singular, although our initial development assumes fis continuous and, usually, several times continuously differentiable. Such integrals occur in a wide variety of physical applications; and the calculation of the coefficients in a Laplace series expansion of a given function (see (4.55)) requires evaluating such integrals.
