**Please note**: this page is intended as a "proof of concept"
demonstration that the input for LiveGraphics3D can be generated using
JavaScript, not a robust application for use by the general public. You
must use correct JavaScript names for any mathematical functions, i.e.
`Math.cos(t)`

instead of `cos(t)`

. The first button
will attempt to graph the surface within the applet on the left; if this
fails, use the second button to graph the surface in a second window.
For more details, or to see how the input is generated, view the source
code of this web page.
