The joint distribution of X and Y is given by f(x,y)= (exp(-y)/y)
I need to compute E(X^2 + Y^2 | Y=y)
can anyone please guide me on how to do this.
Thank You very much for Your help

Using you can calculate the integral
And to find you have to calculate the integral

is f(y) then =exp(-y) or Ei(-y)?
and if f(y) is equal to exp(-y)
equal to [(exp(-2y)x^3)/3y]+[y^2] ?
really appreciate the help
