Cross Product
Cross
Product
is
a
computation
that
involves
the
multiplication of
two
vectors.
However,
unlike
dot
product,
it
resulted
in
another
vector
that
signifies the
direction
of
a
normal
vector
which
is
derived
from
the
computation of
the
two
vectors.
A
normal
is
a
vector
that
is
perpendicular
to
the
two
intersecting
vectors
with
maximum of
two
directions which
is
opposite to
each other (e.g.
left and right).
The direction of
the
two
vectors
and
its
cross
product can
be
represented by
the
right-hand rule.

The formula of Cross Product:
u x v = |u| |v| sin ?, where
•
u = first vector
•
v = second vector
•
|u| = length of first vector
