Curl of curl of a vector field

WebA Curl Calculator works by using the vector equations as inputs which are represented as F → ( x, y, z) = x i ^ + y j ^ + z k ^ and calculating the curl and divergence on the equations. The curl and divergence help us understand the rotations of a vector field. What Is Divergence in a Vector Field? WebI believe I can just sample two nearby points, subtract the second from the first and divide by the distance. Is that correct? And if so, what do I do with this to get the curl formula to work? In my head, it seems like it would be something like: Derivative = (Point2-Point1)/Distance;Curl = Derivative.x - Derivative.y Is that even close to right?
