A function is defined over (0,4) by We then extend it to an even periodic function of period 8 and its graph is displayed below. 1.5 O.S The function may be approximated by the Fourier series f(m) = (to l 230:1 (an cos (\":1\") + bn sin (%)) where L is the half-period of the function. Use the fact that f(m) 51%?) is an odd functions, enter the value of bn in the box below. b\": O.|:1,forn=0,1,2,... Hence besides the constant term, the Fourier series made up entirely of cosines. Calculate the following coefficients of the Fourier series and enter them below in Maple syntax. 0.0 = 9/24 I: a21c1 = E \"2k = El fork=1,2
