Triple Vector Product

The triple vector product , which can also be written in the form , is one way of multiplying the three vectors , , . The result is a vector lying in the same plane as and . Here the vector triple product is shown in red, and the vector is also shown in magenta. The blue plane is the plane determined by and , to which the magenta vector is perpendicular. You can choose to see the unit vector in the direction of with "direction only".
