### Transcript of Graphing Calculator

- 1.The TI-83 (plus) Graphing Calculator

2. Introduction

- 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.

- 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.

- 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

18. Window

- 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.
