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
Graph Format dialog box (displayed using the
menu), select the [Special] tab, tap 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 “Auto” is specified for View Window
parameters, the ClassPad calculates appropriate parameters and configures View Window
settings accordingly.
