WebThe circulation per unit area is the integral divided by the area of the rectangle, which is ΔxΔy. Half of the numerator is multiplied by Δy and half is multiplied by Δx. If we separate these into two fractions, we can cancel the Δy in the first fraction with the Δy in the demoninator F2(a + Δx, b)Δy − F2(a, b)Δy ΔxΔy = F2(a + Δx ... 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 ...
