Graphing Calculator

  1. 1. The TI-83 (plus) Graphing Calculator
  2. 2. Introduction <ul><li>We will look at various properties and settings of the graphing calculator. </li></ul><ul><li>And we will look at how to change those settings . </li></ul>TI 83 Plus Calculator
  3. 3. Turning the calculator on and off. <ul><li>Press the on button to turn it on and “ second” off to turn it off. </li></ul>Ti-83 (plus) Graphing Calculator
  4. 4. Home Screen <ul><li>The home screen is where calculations are performed. </li></ul><ul><li>It is also the starting point to change settings. </li></ul><ul><li>“ Second quit ” always brings you back to the home screen. </li></ul>
  5. 5. Delete Key <ul><li>The delete key deletes one character at a time. </li></ul><ul><li>Insert (second DEL) allows you to insert characters without deleting them. </li></ul>
  6. 6. Clear Key <ul><li>The Clear key erases a line or the entire Home Screen if pushed a second time. </li></ul>
  7. 7. Enter Key <ul><li>This key will carry out any operations that were typed on the screen. </li></ul>
  8. 8. Entry Key <ul><li>Entry key (second ENTER) allows you to display what was entered previously without retyping. </li></ul>
  9. 9. Ans Key <ul><li>This key will repeat the answer without retyping it. </li></ul>(second -)
  10. 10. Arrow Keys <ul><li>Arrow keys move the cursor left, right, up and down. </li></ul><ul><li>When used with the “ second ” key, the up and down arrows darken or lighten the screen </li></ul>
  11. 11. Alpha Key <ul><li>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 . </li></ul>HELLO WORLD
  12. 12. Mode Key <ul><li>The mode key changes the way the results of calculations are displayed. </li></ul>
  13. 14. Math Key <ul><li>The math key will perform functions that are not displayed on the main keypad. </li></ul>
  14. 15. Y= key <ul><li>This is where equations are entered that we would like to have plotted. </li></ul><ul><li>We usually “ Graph ” the functions. </li></ul>
  15. 16. X, T,  , n <ul><li>Used to to type the variable x. </li></ul><ul><li>Ex. Y 1 = 2 x - 6 </li></ul>
  16. 17. Minus and Negative <ul><li>The minus sign is used for calculations. </li></ul><ul><li>Ex. Y 1 = 2x – 6 </li></ul><ul><li>The negative sign is used to indicate the sign of the number </li></ul><ul><li>Ex. Y 2 = - .5x + 4 </li></ul>
  17. 18. Window <ul><li>Determines the size of the graphing screen. </li></ul><ul><li>The default setting is 10 by 10. </li></ul>
  18. 19. A Better Window <ul><li>A better setting for most graphs is 9.4 for x and 6.2 for y. </li></ul><ul><li>This setting makes the graph easier to read. </li></ul>
  19. 20. The Graph Key <ul><li>This is the key we use to see the graph of the equations or “points” that we have entered . </li></ul>
  20. 21. Trace Key The trace key allows us to trace the curve on a graph. Use the arrow keys to move the cursor .
  21. 22. Use the up and down arrow keys to switch between functions . Trace
  22. 23. Zoom Key <ul><li>Zoom settings allow us to change the view of a graph by “zooming” in or out. </li></ul><ul><li>It can also allow us to “zoom in” on a portion of a graph . </li></ul>
  23. 24. Calculate Key <ul><li>“ Second” trace gives us the Calculate key which allows us to determine various values on a graph. </li></ul>
  24. 26. Format Key <ul><li>“ Second” ZOOM gives us the Format key which allows us to change the look of the graph. </li></ul>
  25. 27. Stat Key <ul><li>The Stat Key is used to input statistical data. </li></ul><ul><li>The Stat Key accesses lists similar to columns on a spreadsheet. </li></ul><ul><li>Pressing “1:Edit” brings us to the lists. </li></ul>
  26. 28. Edit Lists <ul><li>Lists allow us to input sets of data and then graph the data and analyze the data. </li></ul>
  27. 29. Stats Plot <ul><li>The stats plot key allows us to choose one of three graphs to plot with the data in the lists. </li></ul>
  28. 30. Plot Menu <ul><li>The plot menu allows us to turn on the data points and determine the type of graph to plot. </li></ul>
  29. 32. The End (for now)
