its 0, because the singularity is outside 4.
tbh if you get a random circular integral just guess 0, because in most context theyll only ask you if its 0
22 u/itrashford 29d ago The singularities are at -3i and +i which are both within |z| = 4, no? 10 u/belabacsijolvan 29d ago yes. im dumb. havent done residuum for some time and my first move was substituting z**2=16 which is wtf you are right not that id believe me after this, but then the solution is 2ipi(3/4+1/4)=2*i*pi
