Transformation 6b
In this figure, is a given transformation, is an arbitrary vector, is on a plane perpendicular to , and the endpoint of is on a line parallel to so that for some . Then , , and .
Note on moving an arbitrary point in 3D. Click on the endpoint of , and arrows appear. Click again and see a different set of arrows. Four arrows show movement parallel to the -plane. Two arrows show movement parallel to the axis.
How does behave "better" when is in the null space of ?
