Green's theorem area formula
WebTo apply the Green's theorem trick, we first need to find a pair of functions P (x, y) P (x,y) and Q (x, y) Q(x,y) which satisfy the following property: \dfrac {\partial Q} {\partial x} - \dfrac {\partial P} {\partial y} = 1 ∂ x∂ Q − ∂ y∂ … WebIt’s called Green’s Theorem : Green’s Theorem If the components of have continuous partial derivatives on a closed region where is a boundary of and parameterizes in a counterclockwise direction with the interior on the left, then Let be the rectangle with corners , , , and .
