At time t = 0, the shape of a wave pulse on a string is given by the function

where x is in meters.

(a) Sketch y(x, 0) versus x. Give the wave function y(x, t) at a general time t if

(b) The pulse is moving in the positive x direction with a speed of 10 m/s, and

(c) The pulse is moving in the negative x direction with a speed of 10 m/s.
