High tide is at 12:00am

Low Tide 6:10pm

High tide returns at 12:24pm

High tide is 5.4m and low tide is .1m

Therefore the amplitude is (5.4-0.1)/2 = 2.65

The mean value is 2.65+0.1=2.75

Therefore

y=2.65cos(Bx+c)+2.75

Im yet to determine B (Period) and c (Phase Shift).

Also, im not sure whether to use cos or sin.
