If we integrate the divergence over a small cube, it is equal the flux of the field through the boundary of the cube. If this is positive, then more field exits the cube than entering the cube.

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.For $\dlvf = (xy^2, yz^2, x^2z)$, use the divergence theorem to evaluate \begin{align*} \dsint \end{align*} where $\dls$ is the sphere of radius 3 centered at origin. Orient the surface with the outward pointing normal vector.The theorem is sometimes called Gauss’theorem. Physically, the divergence theorem is interpreted just like the normal form for Green’s theorem. Think of F as a three-dimensional flow field. Look first at the left side of (2). The surface integral represents the mass transport rate across the closed surface S, with flow outThat is correct. A series could diverge for a variety of reasons: divergence to infinity, divergence due to oscillation, divergence into chaos, etc. The only way that a series can converge is if the sequence of partial sums has a unique finite limit. So yes, there is an absolute dichotomy between convergent and divergent series. ….

Thus, the divergence theorem is symbolically denoted as:By the divergence theorem, the flux is zero. 4 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 surface integral of f over Σ is. ∬ Σ f ⋅ dσ = ∬ Σ f ⋅ ndσ, where, at any point on Σ, n is the outward unit normal vector to Σ.

V.If lim n→∞an = 0 lim n → ∞ a n = 0 the series may actually diverge! Consider the following two series. ∞ ∑ n=1 1 n ∞ ∑ n=1 1 n2 ∑ n = 1 ∞ 1 n ∑ n = 1 ∞ 1 n 2. In both cases the series terms are zero in the limit as n n goes to infinity, yet only the second series converges. The first series diverges.This new theorem has a generalization to three dimensions, where it is called Gauss theorem or divergence theorem. Don't treat this however as a different theorem in two dimensions. It is just Green's theorem in disguise. This result shows: The divergence at a point (x,y) is the average flux of the field through a small circle2. If the interval of absolute convergence is finite, test for convergence or divergence at each of the two endpoints.
