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!
