G a. Plot the value of ( x at) for t = 0, 1/a, 2/a, and t0/a if (s) = sin s. Note that for any t _= 0, the graph of y = ( x at) is the same as that of y = ( x) when t = 0, but displaced a distance at in the positive x direction. Thus a represents the velocity at which a disturbance moves along the string. b. What is the interpretation of ( x + at)?
