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. 
What will be an ideal response?
amplitude = 25, period = 8/3
d = 25 cos  |
