Curl of unit vector
WebHowever, it is a little inelegant to define curl with three separate formulas. Also, when curl is used in practice, it is common to find yourself taking the dot product between the vector curl F \text{curl}\,\textbf{F} curl F start text, c, u, r, l, end text, start bold text, F, end bold text and some other vector, so it is handy to have a definition suited to interpreting the dot … WebThen the unit normal vector is k and surface integral ∬ S curl F · d S ∬ S curl F · d S is actually the double integral ∬ S curl F · k d A. ∬ S curl F · k d A. In this special case, Stokes’ theorem gives ∫ C F · d r = ∬ S curl F · k d A. ∫ C F · d r = ∬ S curl F · k d A.
