Use Formulas to Enter Data in the TI-83 Plus

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

   

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

3. Press

   

   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.
