Divergence theorem examples.

The divergence theorem of Gauss is an extension to \({\mathbb R}^3\) of the fundamental theorem of calculus and of Green’s theorem and is a close relative, but not a direct descendent, of Stokes’ theorem. This theorem allows us to evaluate the integral of a scalar-valued function over an open subset of \({\mathbb R}^3\) by calculating the surface integral of …

Figure 16.5.1: (a) Vector field 1, 2 has zero divergence. (b) Vector field − y, x also has zero divergence. By contrast, consider radial vector field ⇀ R(x, y) = − x, − y in Figure 16.5.2. At any given point, more fluid is flowing in than is flowing out, and therefore the “outgoingness” of the field is negative.These two examples illustrate the divergence theorem (also called Gauss's theorem). Recall that if a vector field $\dlvf$ represents the flow of a fluid, then the divergence of $\dlvf$ represents the expansion or compression of the fluid. The divergence theorem says that the total expansion of the fluid inside some three-dimensional region ... The Divergence Theorem (Equation 4.7.5) states that the integral of the divergence of a vector field over a volume is equal to the flux of that field through the surface bounding that volume.

One function must be greater than or equal to. This sequences has the property that its limit is zero. The other function that we must choose must be less than to or equal to an for all n, so we can use. This sequence also has the property that its limit is zero.

The Divergence Theorem (Equation 4.7.5) states that the integral of the divergence of a vector field over a volume is equal to the flux of that field through the surface bounding that volume. The principal utility of the Divergence Theorem is to convert problems that are defined in terms of quantities known throughout a volume into problems ...The divergence (Gauss) theorem holds for the initial settings, but fails when you increase the range value because the surface is no longer closed on the bottom. It becomes closed again for the terminal range value, but the divergence theorem fails again because the surface is no longer simple, which you can easily check by applying a cut.
