1. the amount of flux per unit volume in a region around some point. 2. Divergence of vector quantity indicates how much the vector spreads out from the certain point. (is a measure of how much a field comes together or flies apart.). 3. The divergence of a vector field is the rate at which"density"exists in a given region of space.C C has a counter clockwise rotation if you are above the triangle and looking down towards the xy x y -plane. See the figure below for a sketch of the curve. Solution. Here is a set of practice problems to accompany the Stokes' Theorem section of the Surface Integrals chapter of the notes for Paul Dawkins Calculus III course at Lamar University.Remark: The divergence theorem can be extended to a solid that can be partitioned into a flnite number of solids of the type given in the theorem. For example, the theorem can be applied to a solid D between two concentric spheres as follows. Split D by a plane and apply the theorem toF ( x, y, z) = ( x, y, z).

The scalar density function can apply to any density for any type of vector, because the basic concept is the same: density is the amount of something (be it mass, energy, number of objects, etc.) per unit of space (area, volume, etc.). Sal just used mass as an example. Bregman divergence.

The divergence theorem is an important result for the mathematics of physics and engineering, particularly in electrostatics and fluid dynamics. In these fields, it is usually applied in three dimensions. However, it generalizes to any number of dimensions. In one dimension, it is equivalent to integration by parts.Remark: The divergence theorem can be extended to a solid that can be partitioned into a flnite number of solids of the type given in the theorem.
