Math Problem Statement
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 [\text{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\cdot\cos(b\cdot t)+d].
At [t=0], the center of the tastiest looking slice is farthest from the door, at a distance of [30\text{ cm}] away. After [2\pi] seconds, it is closest to the door, at a distance of [10\text{ cm}].
Find [P(t)]. [\text{\it{t}}] should be in radians.
[P(t) = ]
