Webso by Cauchy-Goursat theorem, Z C f(z)dz= 0. (2) f is analytic on C \{i,4i}and iis interior to C. So we set g(z) = cosz z−4i which is analytic on and within Cand apply Cauchy integral formula to get Z C f(z)dz= Z C g(z) (z−i)2 dz= 2iπg′(i). Now note that g′(z) = −sinz z−4i − cosz (z−4i)2 and therefore g′(i) = −sini −3i ... WebIntegração complexa. O teorema de Cauchy-Goursat. A fórmula integral de Cauchy.

In mathematics, the Cauchy integral theorem (also known as the Cauchy–Goursat theorem) in complex analysis, named after Augustin-Louis Cauchy (and Édouard Goursat), is an important statement about line integrals for holomorphic functions in the complex plane. Essentially, it says that if is holomorphic in a simply connected domain Ω, then for any simply closed contour in … WebCOMPLEX ANALYSIS COURSE NOTES 1. January 6 Let us quickly recall some basic properties of the real numbers, which we denote by R. Proposition 1.1. Let a,b,c be real numbers. (1) a+b and ab are also real numbers (closure). (2) Addition is associative: a+(b+c)=(a+b)+c. (3) Addition is commutative: a+b = b+a. dr bethany dykes
