Flux integral of a ellipsoid
http://www2.math.umd.edu/~jmr/241/surfint.html WebThe flux form of Green’s theorem relates a double integral over region \(D\) to the flux across boundary \(C\). The flux of a fluid across a curve can be difficult to calculate using the flux line integral. This form of Green’s theorem allows us to translate a difficult flux integral into a double integral that is often easier to calculate.
