Solution The bounds of the integral are determined solely by … Nettet1. aug. 2024 · The integral ∮ C 1 z 2 + 1 d z can easily be shown to be zero when C is a contour that is inside z = 1 since there are no poles enclosed. Interestingly, the integral ∮ C 1 z 2 + 1 d z can also be shown to be zero if C is a contour that embeds z = 1 since the sum of the two residues are 1 2 i and − 1 2 i. 6,141 Related videos on Youtube half up half down dyed hair
