This applet is designed to build intuition about parameterized curves.
- The applet has a control window and Parameterized Curve
control window lets you define x, y, and z as functions of t.
(For curves in 2 variables, z(t)=t is used.) One can also
scroll the point t0. Readouts let you see the values of the point
P0, and the tangent and normal vectors at that point.
parameterized curve window shows the curve along with the point P0
and the unit tangent and normal vectors at that point.
