Fourier Series. Let f(x) be a piecewise linear function on [?L, L] (This means that f(x) may possess a finite number of finite discontinuities on the interval).

The approximation is plotted on a larger interval in Figure 2.1(b), where its periodicity is clearly visible. Example 2.6. Let us compute the Fourier
On the other hand, f needs not to be piecewise continuous to have a Fourier series. It just needs to be periodic. However, if f is not piecewise continuous, then there is no guarantee that we could find its Fourier coefficients, because some of the integrals used to compute them could be improper integrals which are divergent.

28 Nov 2009 in Section 3.8 we look at the relation between Fourier series and Fourier transforms. Using the tools we develop in the chapter, we end up being able to derive Fourier's theorem (which says that any periodic function can be written as a discrete sum of sine and cosine functions) from scratch, whereas we
