Homework Statement
z^-n(e^z-1)^-1 , z not equal to zero
locate the singularities and evaluate the residue.
Homework Equations
The Attempt at a Solution
i don't have an idea about when z is not equal to zero because i think that only singularity point is z=0
hence if there is a special case, i don't have an idea, could you inform me. ? thanks.
