Retains both the spirit and philosophy of the popular First Edition. The primary changes consist of the addition of new material on integral transforms, discrete and fast Fourier transforms, series solutions, harmonic analysis, spherical harmonics and a glance at some of the numerical techniques for the solution of boundary value problems. With more than enough material for a one-semester course, it offers a full presentation of basic principles, and advanced topics are covered in the largely self-contained closing chapters. The order of presentation of some of the material has been rearranged to provide more flexibility in arranging courses.
