Getting Started with the TI–82 or TI–83 Graphing Calculators
1. Press ON to turn calculator on.
2. Press 2nd + to reset calculator. Move cursor down to 3. Press Enter.
3. Scientific Calculator Keys are the Last six rows of keys.
The upper four rows contain Graphing Keys.
ENTER for "=" for subtraction, and (–) for negative numbers.
  and (–) cannot be used interchangeably
4. Enter the following:
a. 18 + 2 ENTER. See 18 + 2 = 20
b. 18 – 2 ENTER. Use the in the last column not (–) See 18 –2 = 16
c. –18 + (–2) ENTER. See –18 + (–2) = –20 Use the (–) key.
^ is the exponential key. Same as xy on a Scientific Calculator
5. Enter the following:
 
6. Put the following expressions in your grapher:
 
7. Key in the following function. (Use the y= Menus)
 
Observe that the equal signs are shaded.
To remove a function, put the cursor on the line containing the function and press Clear. To keep a function, but do not want to graph it, place the cursor over the equal sign and press Enter. Note that the equal sign is no longer shaded.
8.
Select Window. Enter the following: Xmin = –10, xmax=10, xscl = 1, ymin=–10, ymax = 10, xscle= 1 Press graph. You should see the graph. You could have accomplish the above by selecting ZOOM and selecting #6. Note the graph appears right away. This is a much quicker way to graph using what is called the Standard Window. Look at the graph using different windows. Use ± 6 for x and y. Look at the graph in the window for x and y having values of –4 and 4, as well as + and – 2. Which window do you like best?
