Coordinates of a Point Relative to a Basis in 2D
Coordinates of a Point Relative to a Basis in 2D
A basis for is shown along with a point =au+bv. Changing the coordinates and shows how the point moves along a - grid rather than an - grid. Changing the basis vectors and shows how the - coordinate grid and the point with fixed - coordinates depend on the basis vectors.
