Beginning Skills:  Using Tables

Decide first whether you want to choose your own x-values or have the calculator build a complete table.

Also, at least ONE equation must be entered in the y= menu screen.

This is a good option if x-values are more-or-less random, with no equal interval or quite far apart.

  1. Press 2nd- WINDOW keys: That's TBLSET on the top row to see this screen:
    wpe1.jpg (6056 bytes) Ignore all but the line that reads
    "Indpnt: Auto Ask"   Set it to ASK as shown in the window.
  2. Next, press 2nd- Graph  (TABLE).  If you haven't used it before, or used the AUTO mode last, the screen will be almost blank:  tblset.jpg(3765 bytes)The calculator is waiting for a value to be keyed in.  You may enter a number,Pi, e, or even a formula, which will show across the bottom.
  3. The calculator will show the x-value you want and function values for any equations you have listed in the y= screen.  You may have to scroll over using the arrow keys to see all the y-values.

Now for automatic table building.   This is a good option if the values you need are at equal intervals and close together.

  1.     Press TBLSET  (2nd-Window) wpe1.jpg (6056 bytes)
  2.     Place the cursor over the 0 in TblStart and setwpe3.jpg (6245 bytes)
    it to the first x-value you want in your table, here it is 5. Press ENTER.





  3.   If you want the x-values to count by two's,wpe4.jpg (6320 bytes) enter a 2.  If by 50's, enter 50.  You may use any value you wish.  Let's do 2's. Press 2 and ENTER.   





              
  4.     To automatically build a table, set the third line to Auto:wpe5.jpg (6239 bytes)  Leave the Depend: set to AUTO.
  5. Press TABLE ( 2nd-Graph) to see the table. Remember, there must be an equation in the y= screen.table6.tif (1070 bytes)
  6. To see more ordered pairs, use the arrow keys to scroll up or down.
