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.
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.
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!"
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!"
