DERIVATIVES QUESTION D:? An oceanographer measured a set of sea waves during a storm and modelled the vertical displacement of a wave, in meteres, using the equation h(t) = 0.6cos(2t)+0.8sin(t), whwere t is the time in seconds.
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 first occurs.
c) When does the wave first change from a "hill" to a "trough"?
