2) It can be helpful to determine the flux of vector fields through surfaces. With minor changes this turns into another equation, the Divergence Theorem: Theorem 16.9.1 (Divergence Theorem) Under suitable conditions, if E is a region of three dimensional space and D is its boundary surface, oriented outward, then ∫ ∫ D F ⋅ N d S = ∫ ∫ ∫ E ∇ ⋅ F d V. For F = (x y 2, y z 2, x 2 z), use the divergence theorem to evaluate ∬ S F ⋅ d S where S is the sphere of radius 3 centered at origin. Orient the surface with the outward pointing normal vector. The divergence theorem tells us that the flux across the boundary of this simple solid region is going to be the same thing as the triple integral over the volume of it, or I'll just call it over the region, of the divergence of F dv, where dv is some combination of dx, dy, dz. The Divergence Theorem states that if is an oriented closed surface in 3 and is the region enclosed by and F is a vector field whose components have continuous first partial derivatives on and its interior region ,then The divergence theorem is an equality relationship between surface integrals and volume integrals, with the divergence of a vector field involved. It often arises in mechanics problems, especially so in variational calculus problems in mechanics. The Divergence Theorem for Series We will now look at a fundamentally critical theorem that tells us that if a series is convergent then the sequence of terms is convergent to 0, and that if the sequence of terms does not diverge to In vector calculus, the divergence theorem, also known as Gauss's theorem or Ostrogradsky's theorem, is a theorem which relates the flux of a vector field through a closed surface to the divergence of the field in the volume enclosed.

2016-02-18 The Divergence Theorem for Series. We will now look at a fundamentally critical theorem that tells us that if a series is convergent then the sequence of terms $\{ a_n \}$ is convergent to 0, and that if the sequence of terms $\{ a_n \}$ does not diverge to $0$, then the series is divergent.
