Creating a Numerical Table from a Function (TABLE)

TABLE generates a numerical table for x and f(x) using an input f(x) function.
Perform the following steps to generate a numerical table.


1. Press (TABLE) to enter the TABLE Mode.

2. Input a function in the format f(x), using the X variable.

Be sure to input the X variable ((X)) when generating a numerical table. Any variable other than X is handled as a constant.

The following cannot be used in the function: Pol, Rec, , d/dx, Σ.

3. In response to the prompts that appear, input the values you want to use, pressing after each one.

For this prompt: Input this:
Start? Input the lower limit of X (Default = 1).
End? Input the upper limit of X (Default = 5).
Note: Make sure that the End value is always greater than the Start value.
Step? Input the increment step (Default = 1).
Note: The Step specifies by how much the Start value should be sequentially incremented as the numerical table is generated. If you specify Start = 1 and Step = 1, X sequentially will be assigned the values 1, 2, 3, 4, and so on to generate the numerical table until the End value is reached.

Inputting the Step value and pressing generates and displays the numerical table in accordance with the parameters you specified.

Pressing while the numerical table screen is displayed will return to the function input screen in step 2.


Example: To generate a numerical table for the functions f(x) = x2 + 12 for the range -1 ≦ x ≦ 1, incremented in steps of 0.5  (MthIO-MathO)

  • (TABLE)
  • (X)12
  • 1105

Note

You can use the numerical table screen for viewing values only. Table contents cannot be edited.

The numerical table generation operation causes the contents of variable X to be changed.

The specified Start, End, and Step values should produce a maximum of 30 X-values for the numerical table being generated. Executing a numerical table generation using a Start, End, and Step value combination that produces more than 30 X-values causes an error.


Important!

The function you input for numerical table generation is deleted whenever you display the setup menu in the TABLE Mode and switch between Natural Display and Linear Display.
