Question about Texas Instruments TI-89 Calculator
Whenever i try to solve an integrate or a derivative a message appears that says "non-algebraic variable in expression" i do exactly what the guidebook says...i even did the examples it had in it but that message appears in that situation too... what should i do???
If you are using X as your variable try this. Hit the F4 key, press 4 and type X. This will delete the variable x from memory and you should be good to go.
