More vectorcalculus: Gauss theorem and Stokes theorem

Since the divergence of a vectorfield provides us with the number of field lines radiating outward from the source of the vectorfield it can be intuitively understood that the volume integral of the divergenbde of F equals the surface integral … Fortsätt läsa
