The Geometry of 2x2 Matrix Multiplication
The Geometry of 2x2 Matrix Multiplication
In the applet below, dragging points X' and Y' will change the orientation of the transformed coordinate axis. It will also change the
matrix that represents the transformation, as the columns of the matrix are the vectors X' and Y'.
Even though point D and D' have different coordinates, they have the SAME coordinates with respect to their corresponding axis.
