- The divergence theorem
Key concepts
- The divergence theorem relates a surface integral across closed surface
S to a triple integral over the solid enclosed by
S . The divergence theorem is a higher dimensional version of the flux form of Green’s theorem, and is therefore a higher dimensional version of the Fundamental Theorem of Calculus.
- The divergence theorem can be used to transform a difficult flux integral into an easier triple integral and vice versa.
- The divergence theorem can be used to derive Gauss’ law, a fundamental law in electrostatics.

Divergence theorem
For the following exercises, use a computer algebraic system (CAS) and the divergence theorem to evaluate surface integral
for the given choice of
F and the boundary surface
S. For each closed surface, assume
N is the outward unit normal vector.
[T]
S is the surface of hemisphere
together with disk
in the
xy -plane.

S is the surface bounded above by sphere
and below by cone
in spherical coordinates. (Think of
S as the surface of an “ice cream cone.”)
