Curl of cross product
For a function in three-dimensional Cartesian coordinate variables, the gradient is the vector field: As the name implies, the gradient is proportional to and points in the direction of the function's most rapid (positive) change. For a vector field written as a 1 × n row vector, also called a tensor field of order 1, the gradient or covariant derivative is the n × n Jacobian matrix: Webright hand, curl your fingers starting at a and in the direction of b.
