Expand f(x) = x, -7 < x < , in a Fourier series. 2.2.5. (a) Graph g(x) as a 2- periodic function: 1 if - < x < 0, 1 if 0 < x < T. (b) Find the Fourier coefficients corresponding to the function g(x). (c) Write the corresponding Fourier series. (d) How should g(x) be defined at x = -1, x = 0 and x = in order that the Fourier series will converge to g(x) for - x ? 2.2.6. g(x) = = (a) Graph f(x) as a 2L-periodic function: So if -3
