Question 2 3 pts Let En 1 bn sin(wnt) ~ t on the interval t E [0, 1). In order to determine bn, the sum _non sin(wnt) is seen as a Fourier series of an odd periodic function f(t) such that f (t + 2) = f (t). The coefficients bn can be represented as bn = A fo t sin(wnt) dt. Give the value for A = (integer). Detemine _n 1 bn sin(3wn) = (integer). Detemine En-1 bn sin(3wn/2) = (decimal)
