Green's theorem formula
WebGreen's theorem gives a relationship between the line integral of a two-dimensional vector field over a closed path in the plane and the double integral over the region it encloses. The fact that the integral of a (two-dimensional) conservative field over a closed path is zero is a special case of Green's theorem. Green's theorem is … WebNov 28, 2024 · Using Green's theorem I want to calculate ∮ σ ( 2 x y d x + 3 x y 2 d y), where σ is the boundary curve of the quadrangle with vertices ( − 2, 1), ( − 2, − 3), ( 1, 0), ( 1, 7) with positive orientation in relation to the quadrangle. I have done the following: We consider the space D = { ( x, y) ∣ − 2 ≤ x ≤ 1, x − 1 ≤ y ≤ x + 6 }.
