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.

6. Clear Key

  • The Clear key erases a line or the entire Home Screen if pushed a second time.

7. Enter Key

  • This key will carry out any operations that were typed on the screen.

8. Entry Key

  • Entry key(second ENTER) allows you to display what was entered previously without retyping.

9. Ans Key

  • This key will repeat the answer without retyping it.

(second -) 10. Arrow Keys

  • Arrow keys move the cursor left, right, up and down.
  • When used with the second key, the up and down arrows darken or lighten the screen

11. Alpha Key

  • When used in conjunction with other keys, letters are printed out on the screen.The letters are the green ones on the top-right of each key .

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

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.

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.
  • It can also allow us to zoom in on a portion of a graph .

24. Calculate Key

  • Second trace gives us the Calculate key which allows us to determine various values on a graph.

25. 26. Format Key

  • Second ZOOM gives us the Format key which allows us to change the look of the graph.

27. Stat Key

  • The Stat Key is used to input statistical data.
  • The Stat Key accesses lists similar to columns on a spreadsheet.
  • Pressing 1:Edit brings us to the lists.

28. Edit Lists

  • Lists allow us to input sets of data and then graph the data and analyze the data.

29. Stats Plot

  • The stats plot key allows us to choose one of three graphs to plot with the data in the lists.

30. Plot Menu

  • The plot menu allows us to turn on the data points and determine the type of graph to plot.

31. 32. The End (for now)
