Displaying a Graph 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. Window Variables and Y.VARS Menus 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. • Select or deselect parametric equations. • Store values directly to window variables. Exploring Parametric Graphs Free-Moving Cursor The free-moving cursor in parametric graphing works the same as in Func graphing. In RectGC format, moving the cursor updates the values of X and Y; if CoordOn format is selected, X and Y are displayed. In PolarGC format, X, Y, R, and q are updated; if CoordOn format is selected, R and q are displayed. Chapter 4: Parametric Graphing 95
