Fourier Series

Really good book--you need some background knowledge (any introductory analysis book can help with that) but if you've taken more advanced calculus courses this book reads itself!

Lo que he leído del libro a resuelto perfectamente las dudas que me quedaron cuando se pasó este tema en el aula.

Can't say anything wrong about this book. Initially I bought this because I wanted to get a little more out of the PDE. But man, after the reading the first 2 chapters, I was hooked on the subject. The most interesting matter happens in 3, 4 and 5 and after that it gets really really good when he talks about Bessel functions and Eigenfunction methods in the last 2 chapters. I would say this is an excellent book on the subject matter. This is one of those extremely rare books that when you complete a page and flip, you will never have to flip back to recall. The explanation sticks to your mind perfectly. I think that I have understood many other topics well once I learned a little bit about fourier analysis. Some of the ideas such as convergence of fourier-bessel functions and almost every topic in chapter 9 is very well presented and useful in many other classes where particular books skip (or save pages) on these vital topics.

The quality of the pages and the writing is good. The Bessel functions are useful.

Unfortunately I am curently struggeling to really get into this book because of a lack of time, nevertheless the first few pages are very compelling.
