Mustafa is staring at a pizza spinning on a wheel in a glass case.
The pizza is cut into four even slices. The distance P(t) (in cm) between the center of the tastiest looking slice
and the door of the glass case as a function of time t (in seconds) can be modeled by a sinusoidal function of the
form a cos(b. t) + d.
Att = 0, the center of the tastiest looking slice is farthest from the door, at a distance of 30 cm away. After 27
seconds, it is closest to the door, at a distance of 10 cm.
Find P(t).
t should be in radians.
