5. Change of Basis
Changing Coordinates in R2
Standard basis is {e1, e2}
Scalars x1 and x2 are the coordinates of x with respect to the standard basis.
For any basis {y, z} for R2
Scalars and are the coordinates of x with respect to the basis [y, z] .
The vector ( )T is the coordinate vector of xwith respect to [y, z]
