Calculus books dealing with Fourier series

[Electrophy6]

Hey all,
I am looking for **calculus**(and not all these books of Advanced Engineerigng Math or etc...) books dealing with Fourier Series ,its expansions , half reange extensions etc...
I have found that "Stewart'c calculus" includes a chapter dealing generally with Fourier Series but *not * with its expansions

Thanks in advance!

One of the easiest books concerning Fourier Series is Boyce and Diprima's "Elementary Differential Equations and Boundary Value Problems". I think it should count as calculus.

Like Micromass said, any book in differential equations will deal with Fourier Series at a basic level.
