Chapter 3: Graph & Table Application 109

4. Tap [OK] to close the View Window dialog box.

• Tapping $ here graphs the function using the View Window settings.

5. Tap 4.

• This starts summary table generation, and displays the result on the Table window. Note that generation of

a summary table can take a bit of time.

Tip

• The above operation is possible only when “View Window” (which is the initial default) is selected for the Graph Format

dialog box [Summary Table] item.

• A monotone increasing function or other special function may not be solvable by the ClassPad’s internal summary table

calculation. If this happens, use the procedure below.

u To generate a summary table by specifying all of the values for x

1. Tap O and then [Graph Format] to display the Graph Format dialog box.

2. Tap the [Special] tab, and then select a list option (list1 through list6 or a list variable created by you) for the

[Summary Table] item.

• By way of example, here we will select “list1”.

3. Tap [Set] to apply the settings and close the dialog box.

4. Tap O, [Window] and then [Stat Editor] to display the Stat Editor window.

5. In the list you selected in step 2 (list1 in this example), input the values you

want to assign to

6. Tap the Graph Editor window to make it active.

7. On the Graph Editor window, register the function you want to use to create

the summary table.

• Make sure that only the check box of the function to be used for summary table creation is selected. Clear

the check boxes of all other functions on the Graph Editor window.

8. Tap 4.

• This starts summary table generation using the

x-values you input in step 5, and displays the result on the

Table window.

3-4 Using Trace

Trace lets you move a point along a graph and displays the coordinates for the current pointer location.

You can also link the trace operation to the number table used to draw a graph, so the pointer jumps to the

coordinates that are currently selected in the table.

Using Trace to Read Graph Coordinates

Starting the trace operation causes a crosshair pointer to appear on the graph. You can then press the cursor

key or tap the graph controller arrows to move the pointer. The coordinates are displayed as you move the

pointer.

u To perform a trace operation

1. On the Graph Editor window, input and store a function, and then tap $ to graph it.

• Here, input

y = x

– 3 into line y1.
