This book presents a self-contained treatment of invaluable analytic methods in mathematical physics. It is designed for undergraduate students and it contains more than enough material for a two semester (or three quarter) course in mathematical methods of physics. With the appropriate selection of material, one may use the book for a one semester or a one quarter course. The prerequisites or corequisites are general physics, analytic mechanics, modern physics, and a working knowledge of differential an integral calculus.
