1. The problem statement, all variables and given/known data ∫dz/(z4+1) integrated over the curve C1(1+i) 2. Relevant equations The only thing we learned in this chapter is Cauchy's integral formula, so I'm assuming that comes in somehow. 3. The attempt at a solution ∫dz/(z4+1) = ∫dz/(z+1+i)(z+1-i)(z-1+i)(z-1-i) Not bad, eh? Where do I go from here.
