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.

You can perform these actions from the home screen or a program.
• Access functions by using the name of the X or Y component of the equation as a
variable.
• Store parametric equations.
