The depth, d, of the tide in a bay is modelled by the formula

d=A+Bcos(Ct+D) where A,B,C and D are constants, d is measured in metres and t in hours.

The time between successive high tides is 14 hours. The maximum depth of the tide in the bay is 5 m and the minimum depth is 1m. Initially the depth is 4m and the tide is coming in

Find A,B,C and D

How do I do this?
