A. Write a sinusoidal function that models the tide depth d (in feet) as a function of the time t (in hours). Let t = 0 represent midnight.(Show your work). b. Find all the times when low and high tides occur in a 24-hour period. (use Desmos to Graph your function to help you visualize this situation)
