Using Table & Graph

•Tapping $ here graphs the function using the View Window settings automatically configured for summary table generation.

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.

kGenerating 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.

u ClassPad Operation

(1)On the Basic Format dialog box, select “View Window” for the [Summary Table] setting, and specify the value you want for [Cell Width Pattern]. This example uses a [Cell Width Pattern] setting of “4 Cells”.

(2)Input the function y = x3 – 3x on the Graph Editor window.

•Generation of summary tables is supported for “y=” type functions only.

•Clear the check boxes of all other functions on the Graph Editor window, if necessary. Select the check box next to y = x3 – 3x and press E.

•If the check boxes of more than one “y=” type functions are selected, the one with the lowest line number (y1, y2, y3, etc.) is used for number table generation.

(3)Tap 6 to display the View Window dialog box.
