With the following code you can display a line from the origin to the
curve endpoint.
If you want to add an arrow head, you need to "forge" it yourself, as
there is no cone primitive AFAIK.

Manipulate[
 Show[ParametricPlot3D[{Sin[u], Cos[u], u/10}, {u, 0, t}],
  Graphics3D[Line[{{0, 0, 0}, {Sin[t], Cos[t], t/10}}]]], {t, 1, 20}]

Arrow3D functionality is available with Presentations, a high quality
50$ package by David Park available at
