Find the distribution of R = A sin θ , where A is a fixed constant and θ is uniformly distributed on ( − π 2 , π 2 ) . Such a random variable R arises in the theory of ballistics. If a projectile is fired from the origin at an angle α from the earth with a speed v. then the point R at which it returns to the earth can be expressed as R = ( v 2 g ) sin 2 α , where g is the gravitational constant, equal to 980 centimeters per second squared.
