  Hint to 6.42: calculate distribution for U_2= Y_1^2 +Y_2^2, (it will be a gamma). And then, calculate the distribution of the square root of U_2 (using any of the 3 methods). Basically, do this problem in two steps, first U_2 and then square root of U_2. Your variable U is just the square root of U_2.
