[Computer] A taut string of length L = 1 is released from rest at t = 0, with initial position
Take the wave speed on the string to be c = 1. (a) Sketch this initial shape and find the coefficients Bn, in its Fourier sine series (16.31). (b) Make plots of the sum of the first several terms for several closely spaced times between t = 0 and τ, the period. Animate your plots and describe the motion.
