  • Here we present a collection of examples of applications of the theory of Fourier series. The reader is also referred to Calculus 4b as well as to Calculus 3c-2. It should no longer be necessary rigourously to use the ADIC-model, described in Calculus 1c and Calculus 2c, because we now assume that the reader can do this himself. Even if I have tried to be careful about this text, it is impossible to avoid errors, in particular in the first edition. It is my hope that the reader will show some understanding of my situation....

  • This book focuses on the Fourier transform applications in the analysis of some types of materials. The field of Fourier transform has seen explosive growth during the past decades, as phenomenal advances both in research and application have been made. During the preparation of this book, we found that almost all the textbooks on materials analysis have a section devoted to the Fourier transform theory. Most of those describe some formulas and algorithms, but one can easily be lost in seemingly incomprehensible mathematics....

  • We can add the terms of a sequence {an } and get an expression of the form: a1+ a2+ a3+ …+ an + … which is called a series and denoted by However what does it mean by the sum of infinitely many terms? Example. We can try to add the terms of the series 1+2+3+…+n+… and get the cumulative sums 1, 3, 6, 10, …, The nth sum n(n+1)/2 becomes very large as n increases

  • In this volume I shall give some guidelines for solving problems in the theories of Fourier series and Systems of Differential Equations and eigenvalue problems. The reader should be aware of that it has never been my intention to write an alternative textbook, since then I would have disposed of the subject in another way. It is, however, my hope that this text can be used as a supplement to the normal textbooks in which one can find all the necessary proofs.
