Solve the problem.

A boy is flying a model airplane while standing on a straight line. The plane, at the end of  a twenty-five foot wire, flies in circles around the boy. The directed distance of the plane from the straight line is found to be
d = 25 cos
where d is measured in feet and t is the time in seconds. If d > 0, the plane is in front of the boy; if d < 0, the plane is behind him.
What is the amplitude? What is the period?
Graph d over two periods beginning at t = 0.
