Solve the problem.An object is propelled upward at an angle ?, 45° < ? < 90°, to the horizontal with an initial velocity of v0 feet per second from the base of a plane that makes an angle of 45° with the horizontal. If air resistance is ignored, the distance R that it travels up the inclined plane is given by the function R(?) = 
[sin(2?) - cos(2?) - 1]. Show that R(?) = 
[sin ?(cos ? + sin ?) - 1].
