I hope this doesn’t break any rules, I’m not trying to solicit here, I’m just wondering what this thing is worth that I bought earlier today.

Everytime I try to integrate my TI-89 Titanium just spits out the same definite integral I gave it.

The new version of the TI-84 plus CE and TI-83 premium CE (the French version) remove all assembly programming functionality from the calculator, which means no games and no advanced apps downloaded from the internet. Whatever you do, do not update past OS 5.4. If you have an old TI-84, you should be fine to update to the latest version, but if you have the plus CE, leave it alone.

Waiting... Please install software now.
ERROR! Press any key to turn unit off. Then turn unit back on.
I can no longer connect to it through TI Connect in order to potentially install software..
TI just keeps telling me to make sure everything is plugged in -_-

Does anyone know why my calculator is giving me a graph than other people in my class. It is showing that there are no values between -1 and 1 when other calculators show there to be a full arc.
It is a ti 85 and most of my classmates have ti 84s
