The vector product of two vectors **A** und **B** is defined
as:

The resulting vector **C** then has the carthesian components:

In the applet above you can see these formulas in action. You can
use the sliders to adjust the length, angle relative to the z-axis,
theta, and angle relative to the x-axis, phi for the vectors **A**
und **B**. The vector product, **A** x **B**, is
automatically calculated and displayed.

Please note: We have to work in 3d when using vector products. To make this more apparent, we are also displaying the projections of the vectors onto the xy-plane.
