Diagnosing and Correcting Error Conditions
The TI-84 Plus CE detects errors while performing these tasks:
- Evaluating an expression
- Executing an instruction
- Plotting a graph
- Storing a value
- Determine the error. The error screens give helpful hints about what may have happened, but the errors are not always fully explained.
- Correct the expression.
Diagnosing an Error
When the TI-84 Plus CE detects an error, it returns an error message with a short description.
| x | y |
|---|---|
| 1:Quit | Displays the home screen |
| 2:Goto | Displays the previous screen with the cursor at or near the error location |
Note: If a syntax error occurs in the contents of a Y= function during program execution, then the 2:Goto option returns to the Y= editor, not to the program.
