hi, i have a pretty nasty double integral which i need to solve numerically but mathematica gives me error messages when i try to solve it straightforward using NIntegrate the integrand is: Exp[-I*\[Lambda]*(x+y)]*(x-y)*((Sinh[Pi*(x+I*\[Epsilon])]*Sinh[Pi*(y-I*\[Epsilon])])^-2 -(Sinh[Pi*(x-I*\[Epsilon])]*Sinh[Pi*(y+I*\[Epsilon])])^-2) in the limits x=-infinity..infinity, y=-infinity..infinity with epsilon==>0 i'm new to mathematica and will appreciate any suggestions
