Copy of Unit Tangent, Normal, and Binormal Vectors

This applet shows the unit tangent, normal, and binormal vectors at a point on a space curve. Drag the "t" slider to move the point along the curve. The "len" slider can be used to change the length of the vectors [b]T[/b], [b]N[/b], and [b]B[/b] for visibility (though they will not be unit vectors unless len is set to 1). The number kappa (K) is the curvature of the curve at the specified point.[br][br]You can view a different space curve by changing the parametric functions [math]f(t)[/math], [math]g(t)[/math], and/or [math]h(t)[/math].
