WebMar 24, 2024 · Green's theorem is a vector identity which is equivalent to the curl theorem in the plane. Over a region in the plane with boundary , Green's theorem states (1) where the left side is a line integral and the right side is a surface integral. This can also be written compactly in vector form as (2) WebHere is a clever use of Green's Theorem: We know that areas can be computed using double integrals, namely, ∫∫ D1dA computes the area of region D. If we can find P and Q so that ∂Q / ∂x − ∂P / ∂y = 1, then the area is also ∫∂DPdx + Qdy. It is quite easy to do this: P = 0, Q = x works, as do P = − y, Q = 0 and P = − y / 2, Q = x / 2.
