1. The problem statement, all variables and given/known data 3. The attempt at a solution So there are poles at: z=[tex]\pm2[/tex] and at z= -1 of order 4. Right? My query is, when evaluating these poles (using the residue theorem), is it right that for (i) Z = 1/2, no residues lie in that contour? for (iii), do all residues lie in the contour?
