## An applet to demonstrate the cross product

You can input two vectors (shown in blue relative to the white
axes) on the right hand side by entering one component at a time. When
you click on "calculate the cross product" button the coordinates of
the resulting normal vector is shown below. When you click the
"display vector" button the new vector perpendicular to the old
vectors should be drawn in green - unfortunately you may need to
change the camera position to get the image to be updated - sorry:(

To get a much better feel for the cross product try this applet at the University of Syracuse, which allows you to vary the two vectors __a__
and __b__ and see what happens to their cross product in real time.
