Definition:
A function that can be written in the form:
f(x) = asin(bx c) + d
f(x) = acos(bx c) + d
or
Where a, b, c, and d are real numbers
At a sea port, the depth of the water, h meters, at time, t hours, during a certain day is given by this formula:
(a) State the: (i) period (ii) amplitude (iii) phase shift.
At a sea port, the depth of the water, h meters, at time, t hours, during a certain day is given by this formula:
(b) What is the maximum depth of the water? When does it occur?
At a sea port, the depth of the water, h meters, at time, t hours, during a certain day is given by this formula:
(c) Determine the depth of the water at 5:00 am and at 12:00 noon.
(d) Determine one time when the water is 2.25 meters deep.
