When you press s, the TI-84 Plus plots the selected parametric equations. It
evaluates the X and Y components for each value of
T (from Tmin to Tmax in intervals of
Tstep), and then plots each point defined by X and Y. The window variables define the
viewing window.
As the graph is plotted, X, Y, and T are updated.
Smart Graph applies to parametric graphs.
