I need to determine an equation that models tidal patterns.
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, I am not sure whether to use cos or sin.
