Use Formulas to Enter Data in the TI-83 Plus

By C. C. Edwards

You can use the TI-83 Plus graphing calculator to enter data with formulas. The figure illustrates how you would place the sequence 10, 20, . . ., 200 in list L1. The formula used in this example is simply x. The initial and terminal values of x are naturally 10 and 200, respectively. And, as you may guess, x is incremented by 10.

To use a formula to define your data:

  1. If necessary, press [STAT][1] to enter the Stat List editor.

  2. Use the

    TI-83's arrow keys

    keys to place the cursor on the column heading where you want your data to appear and press [ENTER].

  3. Press

    The second, STAT, 5, and right arrow keys.

    to access the seq command.

  4. Enter your formula as a function of a single variable, press [.], and then enter the name of the variable and press [.].

    Here the formula is x and the variable is x.

  5. Enter the initial value of your variable, press [.], enter the terminal value of your variable, press [.], enter the increment for the variable, and then press [ ) ].

  6. Press [ENTER] to enter your data in the calculator.
