Hi, I expect, that you use a interpolation function out side of the limits. Mathematica will use a linear extrapolation that is usual wrong.

I was hoping to see a circle or an ellipse. I do get one, if I plot it for one cycle. But the portrait gets messy if I plot it for more than one time period. It seems as though it is straying away from the path. Isn't it suposed to round and round the same circle?. What is the problem here and how to fix it? > > Thanks, > Ram
