To display the current graph format settings, press y
[FORMAT]. Chapter 3 describes the format settings in detail.
The other graphing modes share these format settings.
When you press s, the TI-83 plots the selected polar
equations. It evaluates R for each value of q (from qmin to
qmax in intervals of qstep) and then plots each point. The
window variables define the viewing window.
As the graph is plotted, X, Y, R, and q are updated.
Smart Graph applies to polar graphs (Chapter 3).
You can perform these actions from the home screen or a
program.
• Access functions by using the name of the equation as a
variable.
• Store polar equations.
• Select or deselect polar equations.
• Store values directly to window variables.
