Maxima can't do this integral??? (David Ronis)

Hello David,

I've done this in EuMathT (It has Maxima support)

 >::integrate(%e^(-kappa*r)*sin(k*r),r,0,inf)
 
 Is  kappa  positive, negative, or zero?

 >::positive
 
 Is  k  positive, negative, or zero?
 
 >::positive
 
                                        k
                                   -----------
                                        2    2
                                   kappa  + k

There is no problem, as I could see.
