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. The curl of a field is formally defined as the circulation density at each point of the field. WebThe formula you derived reads u × ( ∇ × v) = ∇ v ( u ⋅ v) − ( u ⋅ ∇) v where the notation ∇ v is called Feynman notation and should indicate that the derivative is applied only to v and not to u.

WebIndex Notation 3 The Scalar Product in Index Notation We now show how to express scalar products (also known as inner products or dot products) using index notation. Consider … WebThis notation is also helpful because you will always know that $\nabla \cdot \dlvf$ is a scalar (since, of course, you know that the dot product is a scalar product). The curl, on the other hand, is a vector. We know one product that gives a vector: the cross product. And, yes, it turns out that $\curl \dlvf$ is equal to $\nabla \times \dlvf$.
