Curl of a vector function

In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space. The curl at a point in the field is represented by a vector whose length and direction denote the magnitude and axis of the maximum circulation.

WebI'm stuck on the notation of the 2d curl formula. It takes the partial derivatives of the vector field into account. I believe it says the "partial derivative of the field with respect to x minus the partial derivative of the field with respect to y", but I'm not certain. Since I'm using noise to drive this vector field, I'd like to use finite ... WebMain article: Divergence. In Cartesian coordinates, the divergence of a continuously differentiable vector field is the scalar-valued function: As the name implies the divergence is a measure of how much vectors are diverging.
