Question: non-negative function g(z) has the property that g ( z ) d z = 1 f(x,y) = g ( s q r t ( x

non-negative function g(z) has the property that g(z)dz=1

f(x,y) = g(sqrt(x2+y2))/sqrt(x2+y2) -

show thatf(x,y) satisfies the conditions for a pdf of two continuous-type random variables X and Y.

Hint: Use polar coordinates.
