Contour integration using residue theorem (quick question)

  1. Apr 28, 2010 #1
    1. The problem statement, all variables and given/known data

    3. The attempt at a solution
    So i have poles at: z=-1 of order 3, z=1 and z=2. For part i), no poles are located inside the contour, therefore the residue is 0. <--is that right to say, that since there are no poles inside the contour, the residue is zero?
