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 !!!
