Question about Texas Instruments TI-83 Plus Calculator

I have a fairly new TI-83. When I enter an equation and hit graph, it gives me an error of invalid, but the equation is still there when I go back. Is there anyway to reset so this feature will work?

You have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If this doesn't do it, please reply to this post and give a sample equation that causes this error.

If the message appears when you try to graph functions deactivate the
statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)

Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

If the message appears in another context, it sure would help knowing the context of the error.

Having gone over a month without a response, I assume turning off the stat plot features did the trick.

This usually happens after the statistical graphs have been used. You should deactivate them. Press [2nd][Y=] (STAT PLOT). Select [4:PlotsOff] [ENTER]. Calculator echoes Done on main screen.

Restart your graphs.

Restart your graphs.
