grrr.....it keeps plugging in 9 for x. like when i'm doing integrals, direvatives, sums, products, limits, and such, it keeps doing it. i pushed "x store x:", but it just kept it 9. what do i need to do?

 

also, y is 8, but the rest of the variables are just variables.

I only have a TI-83+, but I'd reccommend going into memory management and deleting the X variable.

 

I have a program that runs at startup and clears all the variables. Unfortunately I don't know if it would work on an 89.

Can't you just reset it?

Don't reset it. I have a Ti-89 (NOT titanium) and there's a function that allows you to delete variables. That's what you want to do - clear x, y, etc. On the normal 89, you can either clear all the letter variables, or you can delete individual ones (DelVar x would clear x).

the delvar(x) worked. thanx for the help

Yep, anytime.
