This applet is designed to build intuition about cross products of
3-vectors. The vectors are controlled by sliders tied to the coordinates of the two vectors.
- The applet has a control window and 2 graphics windows.
- The first graphical window is the coefficient sliders
window. Dragging the labeled dots will change the coefficients of
the vectors U and V.
- The second graphical window is the cross product window. It
displays the vectors U and V, as well as the cross product vector
UxV. It also displays the parallelogram with U and V as
edges. The magnitude of UxV is the area of the parallelogram.
- The control window gives the coefficients of U, V, and
UxV. It also gives the lengths of these vectors and the cosine of
the angle between U and V.
