Using Table & Graph

Important!

• 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 under
“Generating a Summary Table by Specifying All of the Values for

x

” (page 3-4-14) to

calculate the elements of the summary table. In addition to View Window parameters, you
can also select previously stored list data to specify the range of a summary table. On the
Basic Format dialog box (displayed using the [Setup] menu), select the [Cell] tab, click the
“Summary Table” down arrow button, and then select the name of the list you want to use
on the menu that appears.

• If you draw a graph or generate a summary table while “Undefined” is specified for View

Window parameters, the ClassPad calculates appropriate parameters and configures View
Window settings accordingly.

k Generating a Summary Table Using View Window

With this method, the summary table is generated using the range you define for the View
Window “xmin” and “xmax” parameters.
