Let (-1 - j), (3 - j), (3 + j) and (-1 + j) be the vertices of a rectangle C in the complex plane. NettetStep 1/1. Answer:To evaluate the given complex contour integral ∮ C z ( 2 z − 1) n d z, where C is the unit circle, we can use the Cauchy Integral Formula. The Cauchy Integral Formula states that for a function f (z) that is analytic on a simple closed contour C and a point z0 inside C, the value of the integral of f (z) around C is given ...

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 Nettet2. mar. 2024 · ∫ C 1 z d z = 2 π i where C is the unit circle with the origin at its center.
