Divergence theorem examples
Example 16.9.2 Let ${\bf F}=\langle 2x,3y,z^2\rangle$, and consider the three-dimensional volume inside the cube with faces parallel to the principal planes and opposite corners at $(0,0,0)$ and $(1,1,1)$. We compute the two integrals of the divergence theorem. The triple integral is the easier of the two: $$\int_0^1\int_0^1\int_0^1 2+3+2z\,dx\,dy\,dz=6.$$ The …The 2-D Divergence Theorem I De nition If Cis a closed curve, n the outward-pointing normal vector, and F = hP;Qi, then the ux of F across Cis I C (Fn)ds Remark If the tangent vector to the curve Cis hx0(t);y0(t)i, the outward-pointing normal vector is hy0(t); x0(t)i, so the ux is I C hP;Qihdy; dxi= I C P dy Q dx Theorem The ux of F across Cis ...

This theorem, like the Fundamental Theorem for Line Integrals and Green’s theorem, is a generalization of the Fundamental Theorem of Calculus to higher dimensions. Stokes’ theorem relates a vector surface integral over surface S in space to a line integral around the boundary of S. 15.7E: Exercises for Section 15.7; 15.8: The Divergence TheoremYour calculation using the divergence theorem is wrong. $\endgroup$ – David H. Mar 24, 2014 at 6:12 $\begingroup$ Many thanks for everything David. I'll retry my solution for the divergence theorem portion and post an answer if I get it.

We say that a domain V is convex if for every two points in V the line segment between the two points is also in V, e.g. any sphere or rectangular box is convex. We will prove the divergence theorem for convex domains V.Since F = F1i + F3j+F3k the theorem follows from proving the theorem for each of the …Example F n³³ F i j k SD ³³ ³³³F n F d div dVV The surface is not closed, so cannot S use divergence theorem Add a second surface ' (any one will do ) so that ' is a closed surface with interior D S simplest choice: a disc +y 4 in the x-y SS x 22d plane ' ' ( ) S S D ³³ ³³ ³³³F n F n F d d div dVVV '

EXAMPLE 14.2.4. Determine whether the series • Â n=1 1+ k n n converges. Solution. This time using using one of our key limits (see Theorem 13.2) lim n!• an = lim n!• 1+ k n n = ek 6= 0. By the nth term test for divergence (Theorem 14.2.2), the series • Â n=1 1+ k n n diverges. EXAMPLE 14.2.5. Determine whether the series • Â n=1 n ...Another way of stating Theorem 4.15 is that gradients are irrotational. Also, notice that in Example 4.17 if we take the divergence of the curl of r we trivially get \[∇· (∇ × \textbf{r}) = ∇· \textbf{0} = 0 .\] The following theorem shows that this will be the case in general:divergence theorem is done as in three dimensions. By the way: Gauss theorem in two dimensions is just a version of Green’s theorem. Replacing F = (P,Q) with G = (−Q,P) gives curl(F) = div(G) and the flux of G through a curve is the lineintegral of F along the curve. Green’s theorem for F is identical to the 2D-divergence theorem for G.
