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 theorem is sometimes called Gauss’theorem. Physically, the divergence theorem is interpreted just like the normal form for Green’s theorem. Think of F as a three-dimensional flow field. Look first at the left side of (2). The surface integral represents the mass transport rate across the closed surface S, with flow out
