To get a general idea of what the curve looks like eliminate the variable t.

this gives

Recall that

Give this a shot and try back if you are still stuck. - Sep 17th 2012, 07:19 PMallstar2Re: sketching a plane curve

This is what I have so far. I am not sure how to sketch each of the position vectors.
