I'm using "assume"  Here's the code and the output

DiceZero := proc (Rmin, Rmax) options operator, arrow; 2*(int(int(r0^3/(r0^3+r1^3), r0 = Rmin .. r1), r1 = Rmin .. Rmax))/(Rmax-Rmin)^2 end proc

> DiceZero(Rmin,Rmax);#doesn't work despite adequate assumptions

undefined/(Rmax-Rmin)^2

 

 

I can upload the real mw-file tomorrow
