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. The divergence of a tensor field of non-zero order k is written as , a contraction to a tensor field of order k − 1. WebFeb 28, 2024 · The curl of a vector field is a measure of how fast each direction swirls around a point. The curl formula is derived by crossing the gradient with a vector and finding the determinant of...

WebDetermine whether the following vector field is conservative on \( R^{3} \). If so, determine a potential function \[ F=\left\langle 3 x^{3}, 4 y^{4},-6 z\right) \] Select the correct choice below and fill in any answer boxes within your choice. A. The field is conservative. Assuming the arbitrary constant is 0 , the potential function is B. 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.
