I have a question about line integrals of vector fields being positive negative or zero. If you are measuring the work it takes to push a point on the curve through the vector field does this The divergence of the above vector field is positive since the flow is expanding. In contrast the below vector field represents fluid flowing so that it compresses as it moves toward the origin. Since this compression of fluid is the opposite of expansion the divergence of this vector field is negative.Try this as a good mental exercise to test if you understand what divergence represents Imagine a three-dimensional vector field and picture what points of positive
Determine whether the divergence of each vector field (in green) at the indicated point (in blue) is positive negative or zero.Benutzerbewertung 100100
