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.
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!"
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.
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.
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...
To use a Texas Instruments TI-89 to pass a calculus exam, either easily or with difficulty, that would otherwise be impossible to do in the normal fashion.
I 89ed that test the whole way through, it was so easy then.
I am going to 89 my way through calc 4, I can't do double integrals .
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!!!
