Green's theorem area
WebJan 31, 2015 · Find the area enclosed by γ using Green's theorem. So the area enclosed by γ is a cardioid, let's denote it as B. By Green's theorem we have for f = ( f 1, f 2) ∈ C 1 ( R 2, R 2): ∫ B div ( f 2 − f 1) d ( x, y) = ∫ ∂ B f ⋅ d s So if we choose f ( x, y) = ( − y 0) for example, we get WebThis marvelous fact is called Green's theorem. When you look at it, you can read it as saying that the rotation of a fluid around the full boundary of a region (the left-hand side) …
