HINTS FOR TROUBLESHOOTING YOUR CALCULATOR:
•
If you lose your L1, L2, etc. , you may reinsert them using STAT 5 (setup editor) enter.
•
The SCATTER PLOT will not show unless Plot 1 has been turned on and there is data in L1 and L2.
Turn off/on scatter
plots by using the arrows to highlight the item you want off/on and using the enter key to change the status.
•
DIM MISMATCH error usually means that the lists in L1 and L2 are not of equal length.
•
DATA TYPE error usually means that you already have something in Y1 and you need to clear it before you can paste a
new equation.
•
INVALID DIM error usually means that your plot(s) are on, but that you have no data in the lists.
Refer to the second
hint above.
•
If your batteries die, raise your hand and hold up your calculator.
If your instructor has an extra calculator available,
he/she will loan it to you for a few minutes.
