My TI-83 calculator doesnt gives me the solutions for tangents that have a negative number. Ex. tan(-1) -5/2

Once you reset your calculator, everything should be fine. Sometimes your calculator's memory stores your cos, tan, and sin and messes up your calucations.T o reset your calculator:
  1. Press 2nd then MEM (which is above the + key)
  2. Press 7 to reset
  3. Press 2 for default
  4. Press 2 again to reset defaults
  5. Press enter
  6. Done.
You should be able to get the answer for that, which is 3.8935, in radians at least. :)

When typing on a ti-83 i couldnt go up to see older work. fix it.

The only way you can enter text in the TI83PLUS is through the program application. However, I have a hard time understanding what kind of funny story is worth typing with such an awkward, uncomfortable excuse of a keyboard.
Joking aside, if your text has been saved you can access it as follows:
Press [PGRM][EDIT] and select program name in the list.

Hope it helps.

Ti-83 calculator went through wash

Best thing to do is to let it air dry. If you want to TRY to speed things up. Let it sit in a bowl of dry rice. The rice help to soak up the water. If you can take the back apart from the front and lay them down (insides facing the rice) on the rice, do it, but do it VERY EXTREMELY carefully. Do not push it down onto the rice, you'll damage the circuit boards. Let it sit for 6 - 8 hours. If still unresponsive, it's gone. Sorry!
