Tangent plane to a parametrized surface
In the pane on the right, drag the blue dot within the -square to see how a surface is parametrized with the variables and .
You can also change the bounds on and , and you can change the functions , , and .
The plane tangent the surface at the point (corresponding to ) is perpendicular to the cross product evaluated at the point .
