      Because sin(m x/xmax) is an orthogonal function in the region 0 ≤ x ≤ xmax, the only time that this integral is non zero is when m = 4. We have just shown3 that the integral of sin2(m x/xmax) between x = 0 and x = xmax = xmax/2 so that equation [16] tells us that Cm = 1 when m = 4 and Cm = 0 …
