Tangent surface
of the twisted cubic:
of a rational curve of degree 4: Other: |
View with equal segment lengths:
The twisted cubic curve is lightly sketched in dark blue on the surface. In the portion shown here, we have -1 < t < 1, while the range of u-values varies with t in such a way that a tangent line segment of length = 2 is shown for each value of t. The midpoint of each tangent line segment is at the point of tangency on the twisted cubic curve.

Viewing suggestions: I recommend long diagonal mouse motions. (Upper left to lower right, for instance.) |
