Step-by-step explanation:
The function can be ...
D(t) = A +Bcos(C(t-p))
where A is the average depth (55+12)/2 = 33.5 cm,
B is the peak deviation from average, 55 -33.5 = 21.5 cm,
C is the horizontal scale factor (2π/T) = (2π/3) for a period (T) of 3 seconds,
and p is the phase offset, given as 1.1 seconds.
The function is ...
D(t) = 33.5 +21.5cos(2π/3·(t -1.1))
