Change the WINDOW settings as shown, then re-graph the plane curve. Watch as the curve is drawn; the orientation (direction) of the plane curve is evident during the graphing.
With a better domain we can see that the plane curve is a parabola with a clockwise orientation. TRACE will allow you move along the graph. At each point, the value of t and the coordinates x and y will be displayed.
