Homework Equations
The Attempt at a Solution
I have no idea where to start on this one... It came up in an exam for a class dealing with functions of several variables (eg, f(x,y,z)) so I don't think it's a usual substitution problem...
I tried writing it as [tex]\int t^x \ln(-t) dt[/tex] (minus the same for y) but I couldn't get any further...
Do I perhaps have to find some taylor polynomial or something?
