(1) The divergence theorem is a mathematical statement of the physical fact that, in the absence of the creation or destruction of matter, the density within a region of space can change only by having it flow into or away from the region through its boundary. Terminology. Use the Divergence Theorem to calculate RRR D 1dV where V is the region bounded by the cone z = p x2 +y2 and the plane z = 1. Because E E is a portion of a sphere we'll be wanting to use spherical coordinates for the integration. In general, the ux of the curl of a eld through a closed surface is zero. Algorithms. It can not directly be used to calculate the flux through surfaces with boundaries, like those on the right. By the divergence theorem, the ux is zero. 4 Similarly as Green's theorem allowed to calculate the area of a region by integration along the boundary, the volume of a region can be computed as a ux integral: take the vector eld F~(x;y;z) = [x;0;0] which has divergence 1 . When you are trying to calculate flux it is easier to bound the interior of the surface and assess a volume integral rather than assessing the surface integral directly through the divergence theorem. The solid is sketched in Figure Figure 2. Applying the Divergence Theorem, we can write: By changing to cylindrical coordinates, we have Example 4. hi problem for 46 using the divergence serum, we got the triple integral or volume integral of three X squared Y plus four TV. dS, that is, calculate the flux of F across S.
