- 1.The TI-83 (plus) Graphing Calculator
- We will look at variousproperties and settingsof the graphing calculator.
- And we will look at how tochange those settings .
TI 83 Plus Calculator 3. Turning the calculator on and off.
- Press theonbutton to turn it on and second offto turn it off.
Ti-83 (plus) GraphingCalculator 4. Home Screen
- The home screen is where calculations are performed.
- It is also the starting point to change settings.
- Second quit always brings you back to the home screen.
5. Delete Key
- The delete key deletes one character at a time.
- Insert(second DEL) allows you to insert characters without deleting them.

HELLO WORLD 12. Mode Key
- The mode key changes the way the results of calculations are displayed.
13. 14. Math Key
- The math key will perform functions that are not displayed on the main keypad.
15. Y= key
- This is where equations are entered that we would like to have plotted.
- We usually Graph the functions.
16. X, T, , n
- Used to to type the variablex.
- Ex.Y 1= 2x- 6
17. Minus and Negative
- The minus sign is used for calculations.
- Ex.Y 1= 2x 6
- The negative sign is used to indicate the sign of the number
- Ex. Y 2= - .5x + 4
- Determines the size of the graphing screen.
- The default setting is 10 by 10.
19. A Better Window
- A better setting for most graphs is 9.4 for x and 6.2 for y.
- This setting makes the graph easier to read.
20. The Graph Key
- This is the key we use to see the graph of the equations or points that we have entered .
21. Trace Key The trace key allows us to trace the curve on a graph. Use thearrow keysto move the cursor . 22. Usethe up and down arrow keysto switch between functions . Trace 23. Zoom Key
- Zoom settings allow us to change the view of a graph by zooming in or out.
