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.

Example:
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!

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.

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.
Example:
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!"

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.
Example:
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.

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.
Example:
"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!"

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.
Example:
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.
