We
can measure how far along an axis
|
|
|
|
provided
by one of the basis vectors a given
|
|
|
v is
by using the inner product operator.
|
|
|
n |
Let v
be defined in the x,y basis and let p,q
|
|
|
|
be
and alternative orthonormal basis. The
|
|
|
|
point
v in terms of p,q is given by the
|
|
|
|
vector
[p.v,q.v]
