parametric curve with velocity vector
Examine a curve defined parametrically.
- Enter coordinate functions for C(t) = ( X(t) , Y(t) ) at top of window [use variable t].
- Enter ends of parameter interval [Lo,Hi] at bottom of window.
A slider specifies number T for point C(T) to be marked on the curve;
animation shows how that point moves as T increases from Lo to Hi.
A checkbox gives an option for the velocity vector at C(T) to be displayed.
