Work out the Fourier series of f, given over one period as follows.
At which values of x does the series fail to converge to f(x)? To what values does it converge at those points?
(h) |cos x| for all x
(k) x on 0<x<1, 1<x<2
Convergence of Fourier Series of Periodic Fuctions is investigated. The solution is detailed and well presented.
