Question about Texas Instruments TI-89 Calculator
I must have done something wrong in the graph function, because now I can´t draw any graphs. I only get the message 'ERROR: window variables domain' when I try.
...with this process you will erase everything....
press "2nd" function and then "Mem"
then press "F1" and choose "3"
Press ok, and then wait, THAT'S IT!

I have the same error. Helping my 16 year old graph a log function. I went to the Texas Instruments web site, typed in "windows variables domain" in the support area and they will walk you through correcting the issue. Eric

You may try to remove the batteries and then press the on-off switch.
