X 2000 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 -1 2000 where I is the height of the rocket. Find the rate of change of the angle of elevation after launch when the camera and the rocket are 5810 feet apart. 0' = 11850 X radians per foot. Round to five decimal places
