divergence of the cross product of two vectors proof

WebWe define the curl of F, denoted curl F, by a vector that points along the axis of the rotation and whose length corresponds to the speed of the rotation. (As the curl is a vector, it is very different from the divergence, which is a scalar.) We can draw the vector corresponding to curl F as follows. WebThe magnitude of the curl vector at P measures how quickly the particles rotate around this axis. In other words, the curl at a point is a measure of the vector field’s “spin” at that point. Visually, imagine placing a paddlewheel into a fluid at P, with the axis of the paddlewheel aligned with the curl vector (Figure 6.54). The curl ... simple driveway gates
