The position (in feet) of a buoy in the water can be modeled

The position (in feet) of a buoy in the water can be modeled by the function s(t) = 9 cos(t) where t is the elapsed time in seconds. (a) If we start viewing the buoy when it is at its high point, how many seconds does it take until the buoy is back at the high point again (i.e. What is the period of the function?)
