Show that any vector V in a plane can be written as a linear combination of two non-parallel vectors A and B in the plane; that is, find a and b so that V = aA+bB. Hint: Find the cross products A X V and B X V; what are A X A and B X B? Take components perpendicular to the plane to show that a = ( B × V ) ⋅ n ( B × A ) ⋅ n where n is normal to the plane, and a similar formula for b.

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
