Generating a Summary Table by Specifying All of the Values for
x
In both of the previous examples, summary table generation is performed using View
Window settings to calculate values for
x
that satisfy the function
f
⬘
(
x
) = 0. With this table
generation method,
x
-values are not calculated automatically.
It is up to you to use a LIST variable to specify all of the
x
-values that appear in the summary
table.
In the example below,
x
-values will be stored in a LIST variable named “list1”, which is then
used to generate a summary table.

ClassPad Operation
(1) On the Basic Format dialog box, select “list1” for the [Summary Table] setting, and

(2) Input the function
y

lowest line number (
y
1,
y
2,
y
3, etc.) is used for number table generation.
