WebProof of Green’s Theorem. The proof has three stages. First prove half each of the theorem when the region D is either Type 1 or Type 2. Putting these together proves the theorem when D is both type 1 and 2. The proof is completed by cutting up a general region into regions of both types. WebSep 29, 2024 · By applying Cauchy's integral formula to the function g ( z) = 1 with z 0 = 0, on the simply-connected domain C, we can find that. 2 π i = ∮ C 1 z d z. Since the value of the contour integral only depends on the values that 1 / z take along the circle C, this result is still valid in our case.
