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. WebAbout this unit. Here we cover four different ways to extend the fundamental theorem of calculus to multiple dimensions. Green's theorem and the 2D divergence theorem do this for two dimensions, then we crank it up to three dimensions with Stokes' theorem and the (3D) divergence theorem.
