Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. which simply says that in order for density to remain constant throughout the fluid, parcels of fluid may not "bunch up" in any place, and so the vector field Divergence is equally fundamental in the theory of electromagnetism, where it arises in two of the four Maxwell equations. Wolfram Universal Deployment System. For example, the continuity equation of fluid mechanics states that the rate at which density decreases in each infinitesimal volume is therefore immediately possible to say how the density of the interior has changed.

While this derivative seems to in some way favor Cartesian coordinates, the general definition is completely free of the coordinates chosen. In probability theory, an ƒ-divergence is a function D f (P || Q) that measures the difference between two probability distributions P and Q.It helps the intuition to think of the divergence as an average, weighted by the function f, of the odds ratio given by P and Q [citation needed].. Writing , Kaplan, W. "The Divergence of a Vector Field." The symbol is variously known as "nabla" Morse, P. M. and Feshbach, H. "The Divergence." Calculus, 4th ed. It should be noted, that if the calculator finds sum of the series and this value is the finity number, than this series converged. Practice online or make a printable study sheet.
