Hi
How do I make Mathematica perform the double integral
Integrate[Integrate[Exp[x]*Exp[y]*p[x,y],{x,-Infinity,Infinity}],{y,-Infinity,Infinity}]

where
p[x_,y_]:=1/(2 Pi s^2 Sqrt[1-r^2])*Exp[-(x^2-2 r s x y +y^2)/(2 s^2
(1-r^2))]
and I know
r is a real, positive number less than 1 s is a real, positive number

Another system gives
Exp[(r+1) s^2]

Regards
Torben M. Hansen
