Web4 Similarly as Green’s theorem allowed to calculate the area of a region by passing along the boundary, the volume of a region can be computed as a flux integral: Take for example the vector field F~(x,y,z) = hx,0,0i which has divergence 1. The flux of this vector field through the boundary of a solid region is equal to the volume of the ... WebSince we must use Green's theorem and the original integral was a line integral, this means we must covert the integral into a double integral.
