Example : To generate a number table for the function f(x) = x2 + ¹₂ for the range -1 ≤ x ≤ 1, incremented in steps of 0.5

1. Press , select the Table app icon, and then press .

2. Configure settings to generate a number table from the function.

3. Register a defining equation for f(x).

4. Configure the number table range setting.

5. Press .

You can configure number table screen settings to show columns for both f(x) and g(x), or for either one of them. To set it, use the menu that appears when you press – [Table Type] while the number table screen is displayed.

The maximum number of rows in the generated number table depends on the Table Type setting. Up to 45 rows are supported for the "f(x)" or "g(x)" setting, while 30 rows are supported for the "f(x)/g(x)" setting.

There are two ways to register defining equations for f(x) and g(x).

While the Table app number table screen is displayed, registering an equation by pressing
– [Define f(x)/g(x)] > [Define f(x)]
– [Define f(x)/g(x)] > [Define g(x)]

While the Table app number table screen is displayed, or while using any calculator app except Ratio and Math Box, registering an equation by pressing
– [Define f(x)]
– [Define g(x)]

The same f(x) or g(x) equation registration screen appears regardless of which of the two above operations is used to register defining equations.

To delete a row

1. On the number table screen, move the cursor to the row you want to delete.

2. Press .

To insert a row

1. On the number table screen, move the cursor to the row that will be under the row you will insert.

2. Perform the following operation: – [Edit] > [Insert Row].

To delete all number table screen contents

On the number table screen, perform the following operation: – [Edit] > [Delete All].

To change the value input in a cell in column x

You can change the value in the currently highlighted x cell. Changing the x value causes the f(x) and g(x) values in the same row to be updated accordingly.

To enter a value into the highlighted x-column cell using: {value of the cell above} +/- {step value}

If there is value in the x cell above the currently highlighted x cell, pressing or automatically inputs into the highlighted cell the value equal to the value of the cell above it plus the step value. So also, pressing automatically inputs the value equal to the value of the cell above less the step value. The f(x) and g(x) values in the same row are also updated accordingly.

f(x) and g(x) values displayed on the number table screen are updated when any of the following occurs.

When is pressed while [Execute] is selected on the Table Range screen.

When the defining equations for f(x) and g(x) are updated (except when a defining equation is a composite function).

When a number is input into column x (including pressing , , in column x).

Note, however, that values are not updated automatically after the following operations.

When the SETTINGS menu is used to change the Angle Unit setting.

When the variable of a defining equation is updated (new numeric value stored) when a defining equation that contains a variable (example: f(x) = 2x + A) is registered.

When the defining equation of a composite function (Example: g(x) = f(x) × 2 - x) is registered, and the defining equation of the reference function (Example: f(x) of g(x) = f(x) × 2 - x) is updated (new defining equation registered).

In these cases, execute – [Recalculate] while the number table screen is displayed to update values.

Doing the following will discard some data and clear some settings of the Table app.

The table below shows which data is discarded and which data is retained.
