Extra Credit: It is a fact that any three-dimensional vector field F can be expressed as a sum of vector fields F- G+H where G is curl-free (i.e. V x G 0) and H is divergence-free (i.e. H O. G and H are respectively called the longitudinal and tranverse parts of F. This is known as the Helmholz decomposition. It is important in electromagnetic theory. At any point in space the longitudinal part of the electric field describes the part...
