The problem presented in this video is:

A plane is flying at a constant altitude of 2 miles, and at a constant rate of 180mi/hr.  A camera on the ground is following the plane as it flies away from the camera.  How fast must the camera rotate to keep the plane in view when the camera is pointed up at an angle of pi/3?
