Geometry of Cross Product

Drag points A and B to change the length and the direction of vectors u and v. What do you observe?
Graphically, the cross product of vectors u and v is a vector perpendicular to the plane containing them. In the applet above, this is represented by vector w. Also, the magnitude of vector w is equal to the area of the parallelogram with u and v as sides.
