Tide height as a function of time resembles a sinusoidal function during the time between low and high tide. At one such location on another planet with water the tide has a high of 10.9 feet at 1 am and then the next low is -1.6 feet at 8 am (7 hours later). Find a formula for a sinusoidal function H (t) that gives the height t hours after midnight. Hm _ \fIA buoy oscillates in simple harmonic motion as waves go past. The buoy moves a total of 10 feet from its high point to its low point, and it returns to its high point every 7 seconds. Write and equation that describes the motion of the buoy, where the high point corresponds to the time t = 0. Mt) = :1
