Using Sketch Menu Commands

This section describes how to use each of the commands on the [Sketch] menu. Note that all
of the procedures in this section are performed in the Graph & Table application, which you
can enter by tapping the T icon on the application menu.

u To plot a point on the Graph window

(1) While the Graph window is active, tap [Analysis], [Sketch], and then [Plot].

(2) Tap the location on the Graph window where you want to plot a point.

• Instead of tapping the Graph window, you could also use the keypad to specify the

coordinates of the point. Pressing a number key displays a dialog box for inputting
coordinates. The value of the key you just pressed is input for the

x

-coordinate. After inputting values for the

x

- and

y

-coordinates, tap [OK]

to plot the point at the location you specified.
