Orientation for Parametric Curves

First of all, I must say that this is product is the best I have found. 
 I am constantly using it in my classes 
from Pre-Algebra all the way through the calculus sequence.

My question is this:  I cannot find a way to show the orientation of
 the curve when I graph a parametric curve.  Am I overlooking 
something or is this feature not available?  I see how to make the
 endpoints of the curve arrows, but I would like to see the direction
 that the curve is traversed as t increases with some sort of arrows 
along the curve.

Thank you for an outstanding product, and I look forward to your reply.

It is not current possible to show the direction of the curve. Actually 
I never thought of this possibility, but it sounds like a good idea, so 
I will put it on my list of things to consider.

Smoothing jagged edges of images

When I use the Copy Image option to copy an graph into Word or Visio the edges
of the graph are quite jagged. Is there a way to generate images with smoother
edges?

It is probably because Word/Vision is using the bitmap image. You may 
want to try Paste special, and choose "Picture (enhanced metafile)". 
Alternatively you can try to save as a metafile in Graph and insert it 
into Word/Vision afterwards.
