Multivariable Calculus

4. Triple Integrals and Surface Integrals in 3-Space

Part B: Flux and the Divergence Theorem

« Previous | Next »

Here we will extend Green’s theorem in flux form to the divergence (or Gauss’) theorem relating the flux of a vector field through a closed surface to a triple integral over the region it encloses. Before learning this theorem we will have to discuss the surface integrals, flux through a surface and the divergence of a vector field.
