In Example 11.1 we had discussed the propagation of a semicircular pulse on a string. Consider two semicircular pulses propagating in opposite directions. At t =0, the displacement associated with the pulses propagating in the +x and in the –x directions are given by

and

respectively. Plot the resultant disturbance at t = R/v, 2.5 R/v, 7.5 R/v and 10 R/v; where v denotes the speed of propagation of the wave.
