Arrows on curves

Hi,

I am plotting a parametric curve in 3D space, and I want to simply
place an arrowhead along the curve to show the curve's orientation.

I tried searching for information on this, and I discovered that there
is a package one could purchase for $50 to get this to work. However,
I am very new to using Mathematica, and thus I'm not sure that I
really need to buy that package at this point. After all, I just want
an arrowhead.

Is there really no way to place an arrow along a curve using the stand-
alone packages? I would find that very strange, considering all the
fancy bells and whistles that Mathematica has.

What if the curve is in 2D instead of 3D? Can we place arrows then?

Thank you,

Will
