Homework Help: Countour integral

  1. Dec 10, 2012 #1
    1. The problem statement, all variables and given/known data
    given 5z^4+z^3+2
    2. Relevant equations

    the question asking me to find the contour integral of thi function in the
    C circle of |z|=1. then how about if the Contour is a square with point [0,0][1,0][1,i][0,i] ?

    3. The attempt at a solution

    i have no idea abt how to do and i attempt to factor up to
    z^4[5+ (1/z) +(2/z^4)] and then juz 2∏i(coefficient of 1/z) am i wrong?
    and i totally no idea of my pole for the square contour [0,0][1,0][1,i][0,i], any one pls help me !!!

    Your function doesn't have any poles. Does it?
