Is it possible to learn, (at least) elementary fourier analysis, after completing Spivak's "Calculus"?. If not, what more is there to learn before one can begin fourier analysis?

However, if I can learn, which text is the best for self learners?

There are various approaches to Fourier analysis though. You can take the theoretical approach or you can focus more on the applications. I don't know why you want to study Fourier analysis??

A full-blown rigorous text is outside your capabilities from now if you only know Spivak calculus. In order to really get it, you need at least real analysis (measure theory, topology,...) and functional analysis (= be familiar with Hilbert spaces and stuff).

However, there is an excellent book out there which I think perfectly suits your needs. It is "Fourier series" by Tolstov. See https://www.amazon.com/dp/0486633179/?tag=pfamazon01-20&tag=pfamazon01-20

I think this is a wonderful first theoretical book on Fourier analysis.

if you look in spivak's calculus itself you will see a glimpse of the beginning ideas plus a recommendation for further reading on fourier analysis.

in the chapter 15 on trig functions, two problems deal with fourier series, including the riemann lebesgue lemma.

then in the suggested reading he recommends courant volume 1, which has only calculus of one variable as prerequisite obviously at the level of courant, i.e. below spivak, and the little book by robert t. seeley, an introduction to fourier series and integrals, which has some "advanced calculus" prerequisite.

If I recall correctly, there is also a nice little elementary introduction in the differential equations book by edwards and penney.

and here's a freebie tutorial:

If you want to learn Fourier analysis as quickly as possible, I think the only prerequisites that you must have is an excellent grasp of the Riemann integral (Lebesgue is not necessary for a first go, even if you want to learn deep theory + rigor) and also a math major's linear algebra course.

I don't mean to be self promoting, but I started blogging at the same time I joined this forum (i.e. since sunday :P). I am blogging about a couple books I am reading through. One of those books is Fourier Analysis by Elias Stein and Rami Shakarchi.

(using this links gives 6% back to these fourms): https://www.amazon.com/dp/069111384X/?tag=pfamazon01-20&tag=pfamazon01-20

This is an excellent book (to be expected since Stein is a coauthor) for Fourier analysis with minimal prerequisites (really just the ones I mentioned). Once you have finished this book, you can advanced to the third book of this series (book 2 is complex analysis, which isn't needed for book 3). Book 3 is real analysis, and introduces measure theory, and "fills" in the theory of Book 1.

Edit: When I say as quickly as possible, I mean in terms of preparation. Not in terms of learning the subject quickly.

Alright, I will check into those books. Thank you everyone :)

Sorry for the late reply by the way.
