    Feedback: -Check the units carefully, particularly inside the trig function. Hints: -What function describes a wave traveling in the positive x-direction that starts with a positive displacement of smax? -Be very careful how you calculate this - if you approximate π as 3.14 you may not be accurate enough, since you are evaluating a trig function of a very small value. -Watch the units - your calculate must be set in radians!
