Summary: FOURIER SERIES, THE SOLUTION TO ALL ENGRG PROBLEMS.
Review: During the course of my studying the book, i discovered that the book goes indepth in making the concept of fourier series analysis simplified. As an engineer i make use of fourier series applications often both in my research work and in the teaching of my students to a great extent i have found this book extremely useful in that it aids the level of understanding. I have also realised that even to a novice that picks up this book will find it very interesting to a large extent.As it is known that fourier series is very usefu in engineering study , especially in the area of solving heat condition problems and for specific applications in engineering design. The book has taken a more comprehensive form which makes reading very easy . I prefer this book because it follows a progressive sequence of explanation.The introduction of fourier integral into the fourier series solution has brought to a great extent the use of partial differential equations in eral life engineering problems . The book has also made the engineering concepts defined practicable, by demonstration of a straight forward attempt aimed at pionting out the extent to which engineerig is usefuk in our everyday lives. This book should be recomended in schools as the true book avalaible in the understanding of the concept of fourier series. Orthogonal function study has also been made in such a way that a first time reader will find it easy in terms of the concept and context.

Summary: Rigor and intuition -- a classic
Review: I learned Fourier analysis on my own, and mostly from this book. Its intuitive content is excellent, but it is a rigorous math text, approaching the subject form an algrbraic viewpoint. He treats convergence issies in detail and in a well-motivated fashion. "Read Who is Fourier" for an intro, and read this for the math behind the intuition.
