Cross Product
A way of multiplying two vectors,
written u × v,
in which the product is another
vector. The cross product of two vectors results in a vector which
is orthogonal to both the
vectors being multiplied. The magnitude of
the cross product of two vectors is found by the formula u × v = u v sin θ,
where θ is the smaller angle between
the vectors.
Note: Cross products are
not commutative. That is, u × v ≠ v × u.
The vectors u × v and v × u have
the same magnitude but point in opposite directions.
