WebFeb 17, 2024 · Green’s theorem states that, ∫ c F. d s = ∫ ∫ D ( δ M δ x − δ N δ y) d A. We will prove Green’s theorem in 3 phases: It is applicable to the curves for the limits … Web3 Answers Sorted by: 9 This is a standard application, a way to use Green's Theorem to compute areas by doing line integrals. Let D be the ellipse, and C its boundary x 2 a 2 + y 2 b 2 = 1. The area you are trying to compute is ∫ ∫ D 1 d A. According to Green's Theorem, if you write 1 = ∂ Q ∂ x − ∂ P ∂ y, then this integral equals
