If U is uniform on (0, 2Ï€ ) and Z, independent of U, is exponential with rate 1, show directly (without using the results of Example 7b) that X and Y defined by
![]()
are independent standard normal random variables.
Example 7b
Let (X, Y) denote a random point in the plane, and assume that the rectangular coordinates X and Y are independent standard normal random variables. We are interested in the joint distribution of R, Θ, the polar coordinate representation of (x, y). (See Figure 6.4)
