Using Table & Graph

SSpecifying all x-values

This method generates a reference table by looking up data stored in a list. A LIST variable is used to specify the x-values. When using this method, it is up to you specify all of the correct x-values required to generate the summary table. The summary table will not be generated correctly if you provide incorrect x-values.

The following shows examples of each of the three available summary table generation methods by generating a table for the function y = x3 – 3x.

Summary Table and Graph of y = x3 – 3x

Tip

•You can control whether or not the summary table should include an f (x) line (quadratic differential component) using the [Summary Table f (x)] setting on the [Special] tab of the Graph Format dialog box (page 1-9-7). Turning on the [Summary Table f (x)] option causes both linear differential components and quadratic differential components to be displayed in the summary table. Turning it off shows linear differential components only.

IGenerating a Summary Table Using Automatically Set x-Values

With this method, the summary table is generated using a range of values from –δto δ.

SClassPad Operation

(1)On the Graph 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”.

• To open the Graph Format dialog box, tap , and then [Graph Format].

•For additional details about Graph Format settings, see “Application Format Settings” on page 1-9-4.

(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 .

•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 to display the View Window dialog box.
