Question: Integration

hi I am new to Maple. I have been trying to solve a nonlinear equation, but have been fraught with problem. I would appreciate any help. Solution through 'solve' would be great but 'fsolve' will be ok too. For the solve eq:=int(E^2/(exp((E-Mu)/KT)-1), E=El..EU)) -int(E^2/(exp((E/KT)-1), E=EL..EU))=0) Typical values of E are 10^-19; and KT is about 10^-15.
