The Fourier series representation, FS(t), of a periodic function of period 4 is given by FS(t) + cos (7) + b&. sim (***) In this particular case the Fourier series coefficients are given by ag- 0.5 An- 4(-1)" Tw 3(1-2(-1)") nx Compute the Fourier series coefficients for n-1,2,3 correct to 4 decimal places and hence, using these entered values, compute FS,(0) correct to 3 decimal places. Enter the values in the boxes below. Enter a correct to 4 decimal places: Enter a correct to 4 decimal places: Enter as correct to 4 decimal places: Enter b, correct to 4 decimal places: Enter by correct to 4 decimal places: Enter by correct to 4 decimal places: Enter FS,(0) correct to 3 decimal places:
