Complex Integration: Lec.- 5(Cauchy's Theorem in Complex Integration)

#Cauchy_theorem#Complex_Integration#, Cauchy's theorem in complex integration has been proved. Also, it has been shown that this is weaker version of Cauchy's fundamental theorem. It has been informed that without imposing the condition of continuity of derivative of f(Z), the theorem can be proved which is known as Cauchy-Goursat theorem.
