Summary: not a good book for physicists
Review: THIS BOOK HAS NUMEROUS ERRORS IN THE EXAMPLES. THE PROFESSOR AND SOME STUDENTS HAVE SOLVED SOME OF THE PROBLEMS IN THE BOOK AND FOUND THAT THE CORRESPONDING ANSWER IN THE BACK IS INCORRECT. THE BOOK DOES A POOR JOB OF TEACHING THE FOURIER SERIES. WE HAVE ALREADY REACHED THE END OF THE SECOND CHAPTER AND I USE OTHER BOOKS CHECKED OUT FROM THE LIBRARY AS HELP. I WOULD THINK THAT NOT EVEN A FIRST EDITION BOOK WOULD HAVE THIS MANY ERRORS. ALSO THE PROOFS ARE WEAK. STAY AWAY FROM THIS TEXT, AND IF YOU LIKE ME USE THIS BOOK FOR A CLASS, FIND SUPPLEMATARY TEXTS TO TAKE THE PLACE OF THIS ONE

Summary: Stay away!
Review: This book has the reputation of being very weak and error-prone. If you have a choice DO NOT get this book. For a third edition, the editing is disgraceful. I don't think I would find similar errors acceptable in a first edition. For example, on page 18, various steps establish A1=0 and A2=0. The very last paragraph on that page uses both A1 and A2 multiplied to various items to derive a solution. Last time I checked, anything times zero is zero, which is what this book would get if Amazon had a "zero rating." The way in which the author "changes the rules" throughout the book leads to confusion, leaving the reader more perplexed than when she picked it up. For example, on page 104 (solving the heat equation), the author states that Lambda must be pure imaginary. If this were true, then the equation he gives cannot have boundedness. Like most folks, you may be forced to use this drek in your PDE class. If so, do your self a favor and pick it up as cheaply as possible (i.e., used) and then dump it as quick as you can once the class is over. Once someone figures out that there are very few good PDE books, he will write one....

Summary: Worked examples and more!
Review: This third edition, from a new publisher, has a number of attractive new features: More worked examples, more than 200 in all, more exercises with answers, more on modern developments such as asymptotic methods, correction of typographical errors,--- and loving care from the editors at Waveland Press. The result is a much nicer appearance, and high quality pedagogical improvements.-- I have taught from an earlier edition of this very nice book. Both the students and I have been happy with it. It is an important and useful topic in math [both pure and applied] , and it is especially relevant and central to the service courses offered by most math departments. Sample of topics: The Green function method, the equations of heat, and of waves, and the PDEs of Laplace and Poisson. Orthogonal functions and Fourier methods. The method of stationary phase, and the classical Sturm Liouvile problems.-- Pinsky's book is the best text for teaching these classical tools. A nice feature of the new edition is an added section on the use of Mathematica in the study of PDEs. When students need to look up one of the classical formulas in the theory of boundary value problems, I often refer to Pinsky's book which has always been on target.
