A television camera at ground level is 2000 feet away from the launching pad of a space rocket that is set to take off vertically, as seen in the following figure. The angle of elevation of the camera can be found by 0 tan where x is the height of the rocket. 0' Find the rate of change of the angle of elevation after launch when the camera and the rocket are 3618 feet apart. = 2000 X 2000 .98509 x radians per foot. Round to five decimal places.
