Please help me with this trigonometry question:
The graph shows the variation of the water level relative to mean sea level in Commencement Bay at Tacoma, Washington, for a particular 24-hour period. Assuming that this variation is modelled by simple harmonic motion, find an equation that describes the variation in water level as a function of the number of hours after midnight.© BrainMass Inc. brainmass.com March 22, 2019, 12:30 am ad1c9bdddf
