Texas Instruments TI-89 Titanium Graphing Calculator - General Information
TI-89 Titanium Features:
The Texas Instruments TI89 Titanium graphing calculator offers new features, it is TI’s most powerful graphing calculator, and comes with built-in advanced mathematics preloaded Apps which enable you to manipulate mathematical expressions and functions (factor, solve, differentiate, integrate, and more). It also includes differential equations, 2-D graphing and data analysis, 3-D graphing with rotations, linear algebra, interactive numeric solver, constants, unit conversions, statistical regressions, and optional assembly language programming.
The Texas Instruments TI89 Titanium graphic calculator is essential for college math, and beyond. Enhanced with Flash technology, a built-in USB port that makes data transfer ultra-convenient, and three times the memory of the original TI-89, the TI89 Titanium provides more storage space so you can store more Apps, data, and programs. The TI-89 Titanium's advanced functionality and 3-D graphing make problem-solving for AP, advanced mathematics, and engineering courses infinitely easier.
All this power is generated by only 4 AAA batteries with a lithium battery backup to protect RAM memory during main battery change. This Texas Instruments TI-89 Titanium graphing calculator comes in an impact-resistant slide case and it is allowed to be used on the AP Calculus, AP Statistics, AP Physics, AP Chemistry, PSAT/NMSQT, SAT® I , SAT II, and Math IC & IIC exams.
TI-89 Titanium - Is this the calculator I’m looking for?:
Are you looking for the Texas Instruments TI-89 Titanium graphing calculator? If your answer is “Yes” there is no need to read the following information. However, if this calculator sounds like the one you need but you are not sure, keep on reading.
If you are not sure because your syllabus, your professor, your classmates, or your friends call it differently, chances are that if it has a “T” and a “9” somewhere in there, this is the one. Over the years we have seen how people call the TI-89 Titanium graphing calculator different names. This has been common ever since Texas Instruments introduced it in the summer of 2004. Some of these names are simple abbreviations but others confuse students when they find the correct calculator but the name or description they were given does not match precisely. Read the following nicknames or common misspelled variations of the “TI-89 Titanium graphing calculator” only if you are confused or for some reason you are still wondering if this calculator is the one you are looking for.
Starting with the most popular nicknames are the TI89 (with a capital “i”), the Tl89 (with a lower case “L”) and the T189 (with a number “1”). Some people confuse it with the original TI-89 (the old model - not the Titanium) and call it the TI-89 (with a capital “i”), the Tl-89 (with a lower case “L”), and the T1-89 (with a number “1”). Others like the sound of “plus” and call it the TI-89+ (with a capital “i”), the Tl-89+ (with a lower case “L”) and the T1-89+ (with a number “1”). However, other people seem to forget a space and call it the TI-89Titanium (with a capital “i”), the Tl-89Titanium (with a lower case “L”) and the T1-89Titanium (with a number “1”). Others don’t forget the space but simply replace the capital “i” which stands for Instruments with a lower case “L” or number “1” and they call it the Tl-89 Titanium or the T1-89 Titanium.
Replacing a character or omitting a space or dash is common. At times however, people do a little bit of both and then some. When this happens people ask about renting t-189, t-89, and t89 scientific calculators. Scientific calculator rentals is something we do not offer for rent at the present time. At this time we offer graphing calculators for rent but not scientific calculators. If you need a “scientific calculator” buying a cheap new or used for around $10 is probably your best option. Assuming you need a “graphing calculator” and leaving the most interesting and controversial “descriptions” for last are the TI-89 Titanium graphic, grafic, grafing, grafting, graphting, graphics, and grafics calculator and sometimes even called calculater (with an “e” at the end).
Luckily, 99.9% of the time all of those descriptions refer to the one and only Texas Instruments TI-89 Titanium graphing calculator. With that said, if this is the calculator you are looking for and would like to receive your calculator rental promptly (calculators are shipped out daily) click on the “Order it now!” button at the top of this page and place your order today.
