# Geometry of Cross Product

Drag points A and B to change the length and the direction of vectors

**and***u***. What do you observe?***v*Graphically, the cross product of vectors

**and***u***is a vector perpendicular to the plane containing them. In the applet above, this is represented by vector***v***. Also, the magnitude of vector***w**is equal to the area of the parallelogram with***w****and***u***as sides.***v*## New Resources
