The Cross Product

The cross product of two vectorsandis also a vector, at right angles to the other two with magnitudewhereis the angle between the two vectors.

The cross product of the two vectors can be written as the determinant of a matrix:

Ifandthen

For example ifandthen

As shown above, if the order of the vectors is reversed, the sign of the cross product changes.
