I'm a college freshmen, and I've just switched from the TI-84 to the TI-89 (titanium) to supplement me through calculus. I've been having some trouble with how to adjust to operating it, though. Mostly having trouble with the y= editor. So I guess I'll just list em off.
How do I insert the Y1 variable into the home screen, there is no VARS key.
I know this thing has a lot more capability than the 84, and I'm sure I'll be glad I'm using this when I get to higher levels of Calculus/Physics(I have to go through IV), but I need to learn how to use it first. Any plain-english reference or guides on how to use would also be appreciated.
Since this also happens to be my first post I guess I'll give a short anecdote of myself. I'm a Physics-Japanese double major, I obviously like math, and my favorite author is Palahniuk. I'll try to help out in the calculus/precal/trig sections when I can.
