Descrierea produsului:

• Includes USB unit-to-unit cable, Connectivity Cable for other TI units and connection software, operating manual Doing complex calculations on a scientific calculator is much easier with the TI 89. Its large screen offers the ability to generate graphs that can illustrate your conclusions. It s especially helpful with statistic functions, such as regression analysis. The TI-89 Titanium includes all the built in functionality and power of the original TI-89. It has an increased amount of Flash ROM 500KB, quite powerful for a traditional handheld design. This is TI s most sophisticated calculator, with such features as 3D graphing, upgradable flash ROM, built-in assembly language programming, and a generous amount of user-available memory. It now includes a mini USB port. This portable symbolic, numeric, and graphing calculator is perfect for advanced mathematics and engineering applications for college and advanced coursework. Its built-in USB port makes data transfer ultra-convenient. Built-in Flash memory for archiving data(2.7MB) Finance tools, Organizer, Polynomial Root Finder, Simultaneous Equation Solver, and many more apps Fully upgradeable (electronically) through its Flash ROM chip (optional TI Graph-Link required) Computer Algebra System, differential equations, 2D-graphing and data analysis, 3D-graphing with rotations, linear algebra, interactive numeric solver, constants, unit conversions, statistical regressions Optional Assembler language Mathematical expressions appear on the display the same way as they are usually written in class or in published texts and academic journals StudyCards and Symbolic Math Guide for helping students learn more effectively Preloaded with Official AP Calculus exam review questions Built-in USB port for easy data transfer between handhelds - The TI Connect allows rapid data transfer to computers

Client Evaluari:

• TI-89 Titanium. I love the calculator, it s only real downside is the fact that the letter size in display is pretty small and not adjustable. Only took me a week to shift to this system from TI-83 Plus.
• Truly Amazing. This calculator will do any and everything you need it to do.
  It takes a bit of learning to get the full use of it, but after that you re good to go. I wouldn t buy anything less than this product.
• Does NOT support Mac OS 10.5 and up!!!. If you only use Mac OS, do NOT buy this calc if you plan to update the calc or upload new programs. It does NOT work and Ti has failed to support the last 2 versions of OS X.
• A great price for an over the top graphing calculator. I wanted a calculator that could help me in my math pre-reqs and not break the bank. Campus bookstore was asking 249.00 for a used ti-89. The Target Store was asking 149.00 for new. My gently used, with new batteries, was around 80.00.
  
  The Ti-89 is way overpowered for a simple class like Probability and Statistics or College Algebra. The Windows like interface makes it so easy to use. The other people in class will be waiting for their calculators to show the answer, while you are 2 problems ahead.
  
  This Ti-89 did not come with a book or cables, but a trip to Best Buy and a local printing shop cost me 15.00 total to fix that.
  
  You have to spend some time in general figuring how to set your parameters and understanding how it functions. After that, you re going to be very happy. In my experience you can count on figuring this out yourself, as my professors use the Ti-84 series for classwork and did not have a good grasp on the more advanced Ti-89.
  
  
• Great Addition to Engineering Tools. Having used a scientific calculator from high school to 4th year in college, this made my life so much easier when solving difficult/cumbersome statistics and engineering problems. Not exactly the easiest calculator to use (why one would need to read the manual to make full use), but by comparison to scientific calcs, it s worth the time to learn how to use.
