Chapter 1: Vector AnalysisIntegral Calculus
In three dimensions we not only have line integrals, but also surface and volume integrals.
The fundamental theorem of divergences relates volume and surface integrals:
- The right-hand side of this equation is called the flux of the vector function through the surface that bounds the volume (e.g. total electric flux).
- The left-hand side of this equation is called the source term of the vector function (e.g. total enclosed electric charge).
