In summary, troubleshooting TI-89 calculator errors involves identifying the specific error message, checking the calculator's battery and memory, and performing a factory reset if necessary. Other potential solutions include reinstalling the calculator's operating system and updating the software. It is also important to ensure that the calculator is being used correctly and that the input is entered accurately. If all else fails, contacting TI customer support or seeking assistance from a calculator expert may be necessary.

i went to this site: http://antaki.ca/TI89Tutorial/#poly
and typed in different commands and none of them seem to be working.
when i integrate sin(x) it just says ".989992"

when i did expand((x+4)^4,x) it just says "2401."
when i do factor(x^2-9,x) it says "0"
so i tried factor(x^2-9=0,x) and it says "true"

the only thing that worked so far is:
solve(x^2-9=0,x) and came out as "x=-3 or x=3"
even though that website didnt tell me to put that in

does anybody know how to fix this?
i have ti-89 titanium OS 3.1 hardware version 4.00

Sounds like you have 3 stored in for x. Type x at the prompt, it should probably give you the value 3. To fix this just press F1... then scroll over to F6. From there, select the option that says "1. Clear a-z"
