• This generates a number table and displays it.
3. Tap a and then [Link].
• This displays the Graph window and draws the graph, with the trace
pointer located on the graph line. The coordinates of the trace pointer
location will also be shown.
• Tapping a cell in the
location of the cell’s value.
• You can move the highlighting in the number table by pressing the up
and down cursor keys, or by tapping the cell you want to select. Doing
so causes the trace pointer to jump to the corresponding location on the
graph.

4. Tap the Graph window to make it active. Next, tap [Analysis] and then
[Trace].
• This causes a pointer to appear on the graph.
5. Use the cursor key to move the pointer along the graph until it reaches a
point whose coordinates you want to input into the table.
6. Press E to input the coordinates at the current cursor position at the end
of the table.
7. Repeat steps 5 and 6 to input the rest of the coordinates you want.
0304
1. In line y1 of the Graph Editor window, input and save x2 – x – 2, and then tap $.
2. Tap [Analysis], [Sketch], and then [Inverse].
• This graphs the inverse function. The message box briefly shows the inverse function.
Tip: If a function does not have an inverse, the graph produced by the [Inverse] command will be the result of
interchanging the
x and y variables of the original function.
0305
1. While the Graph window is active, tap [Analysis], [Sketch], and then [Circle].
• This display “Circle” on the Graph window.
2. Tap the point where you want the center of the circle to be, and then tap a second point anywhere on the
circle’s circumference.
• This draws the circle, and the message box shows the function for the circle.
• You can also draw a circle by specifying the coordinates of its center point and specifying its radius value.
In place of the operation in step 2 of the above procedure, press a number key on the keypad. On the
dialog box that appears, enter the required values and then tap [OK].
0306
1. While the Graph window is active, tap [Analysis], [Sketch], and then [Vertical].
• This display “Vertical” on the Graph window.
2. Press 2.
• This displays a dialog box for specifying the
x-coordinate of the vertical line, with 2 specified as the
x-coordinate.
• Instead of inputting a value here, you can use the stylus to tap the point through which the vertical line
should pass.
3. Tap [OK].
To draw a horizontal line, tap [Analysis], [Sketch], and then [Horizontal] in place of [Vertical] in step 1 of the
above procedure. In the case of a horizontal line, you need to specify the
y-coordinate in step 2.
