All steps must be shown, even small details. Workout the relevant calculations please complete the problem, not just set it up. Provide common sense explanations.
Bonus: The function p(z)=[z(z+1)]^-1 can be written in two different ways:
(see attached for full equation)
These two expansions are contradictory. The first seems to indicate that p(z) has a simple pole at z=0 and the residue is zero. Can you resolve this apparent contradiction? Which statement is correct? (Hint: Try to determine the region in which each expression is valid.)
Answer is in a Microsoft Word attachment.
