What is TI-89?
A device that qualifies colleges for free stuff: By stating that students are required to purchase the TI-89 Titanium on their syllabi, colleges are qualified for free equipment and emulator software from Texas Instruments. (from department minutes)
This device is so remarkable that some students can ace a math class with it, but without it cannot add 1/2 + 1/3.
Dean's secretary: Hey, you didn't put on your syllabus that you require the TI-89 Titanium.
(Dean walks in.)
Instructor: That's right. Doesn't it seem unethical to require students to pay $150 or more for a calculator so the college gets free stuff?
Dean: No, not at all.

TI-89 - what is it?
A high-performance calculator made by Texas Instruments. With a computer algebra system, it can evaluate algebraic expressions symbolically, rather than just giving a number answer; and is therefore much more powerful and difficult to use than the TI-84, the common graphing calculator used by high school and college students alike.
"Hey, Jack, where's your TI-84?"
"OH, I left it in the trash can. Check out this great TI-89 Titanium I just got! I won't even have to know how to do math anymore!"
What does "TI-89" mean?
An upgraded version of the TI-89 released by Texas Instruments in 2004. Features a new mini-USB port and 2.7 megabytes of flash ROM.
n00b: lol, check out my hip TI-89! I have 6 games on it! I am cool!
1337 h4x0r: stfu n00b, I have a titanium, I have 50 games.
TI-89 - what does it mean?
God's calculator. Most of the questions of the SATs that require solving for variables or solving trigonometric identities can be solved by simply plugging them in to this beast of calculator.
John: "Hey Randall, what did you get on the math section of the SATs?"
Randall: "Oh, just an 800"
John: "800?!?! Didn't you get a 550 last time?"
Randall: "That was before I got my TI-89 Titanium!"
TI-89 - meaning
The ultimate calculator capable of calculating anything and everything
Holy shit! Is that a ti-89?!
TI-89 - definition
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!!!
TI-89 - slang
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!
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.
TI-89
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
