The "L" button takes you to an On-Screen Laboratory^® where you can practice, given randomly generated data, the geometry and mathematics associated with this subject. In the present case, there are Labs on the direction of the cross product vector "C" and on its magnitude, given "A" and "B" in the geometric representation.

The "T of C" and "Map" buttons take you to the Table of Contents page and to a "roadmap" page. They are always available for you.

There are hypertext links to related material. (The ones you see in the page shown are not active; the picture above is only a screen snapshot.)
