Using Table & Graph

kTable Generation Precautions

•Table generation is performed using the currently selected function that is of the current function type selected on the Graph Editor window toolbar.

Current function type

•Though the selected current function type is “y=” in the above screenshot, there is no “y=” type function selected on the Graph Editor window. Tapping # to generate a table when the above condition exists causes the error message “No Functions Selected” to appear.

•An inequality cannot be used to generate a table.

Editing Number Table Values

Changing an x-value in the number table automatically calculates and displays the corresponding y-value.

Example: To change the x-value in line 3 of the number table from –1 to –2.5

To generate a table, see “To generate a number table by specifying a range of values for x using the Table Input dialog box” on page 3-4-2.

u ClassPad Operation

(1)Tap the cell in line 3 of column x of the number table to select it.

(2)Perform the key operation: z2.5.

•Pressing zcauses the Enter Value dialog box to appear with a minus sign (–) in the [x-value] input box. Continue with the rest of the key operation to input the required value, and then tap [OK]. This changes the value in the selected cell to the one you input.

The y-value is updated automatically in accordance with the new x-value.
