1. A far superior model to its counterpart, the ti-83
. Can graph 3D functions, differentiate and integrate and calculate Taylor series. The symbol of a true math or science geek.
2. The main reason I'm passing college math.
1. I really need to get a ti-89. This crap is too hard.
2. I LOVE MY TI-89!!!
a secret organization only known by those who have a calculator of the same name. While other math students fumble with equations, the TI-89er relaxes as s/he's just used the solve() function. And as all the other dumbasses observe, s/he simple responds "TI-89," and other students will simply cower and look elsewhere.
Oh, the TI-89's? Well, if I told you I'd have to kill you.
The ultimate calculator capable of calculating anything and everything
Holy shit! Is that a ti-89?!
Graphing calculator that has the meaning of life. Not only does it do math for you, but it also does your laundry!
The AP board is examining your test, and sees that you miraculously have the answer in one step. The justification is "Ti-89".....automatic 5!
Definition: the Texas Instruments 89. Known by every student in American high schools as an Original Game Boy, that also can graph differential equations and keep useful notes for tests.
Alternate Definition: a Dell
"Dude I just got the best game for my TI-89, f-ing Track and Field 1998!"
"Oh man you're so lucky, I still have only an 83, but I got Pimp Quest, mother f-er."
The main reason college students fail calculus classes.
The professor warned us not to rely on our ti-89's...but it was always so damn handy...
a high-end graphing calculator from Texas Instruments capable of 3D graphing, computing definite and indefinite integral
s and derivate
s among with numerous useful features.
a: did you get that second problem from last night's homework?
b: yea, of course.
a: how? we didn't learn how to integrate logarithmic functions yet!
b: we didn't but my ti89 did!
a: you bastard!
