Let f(x) be a function of period 27 such that f(x = TT - 2 , - TT

Let f@) be a function of period '27T such that (1.1) (1.2) (1.3) (1.4) Sketch the graph of on the interval (2T, '27). Determine the Fourier series of f (x) on the interval (7, T). To what value cloes the Fourier series converge at a: 0? By choosing an appropriate value for at, show that k odd
