a) Determine the vertical displacement of the wave when the velocity is 0.8m/s

b) Determine the maximum velocity of the wave and when it occurs.

c) When does the wave first change from a hill to a trough? Explain.

Ans: I tried finding the part a) by first finding the derivative, then how do i go about simplifying it. how do i find the max velocity with cos and sin in the function?
