11 of 12 people found the following review helpful Great Advanced Calculator, Highly Recommended!, June 15, 2010 By  C. F. Hill "CFH" (South-Central, PA USA) - See all my reviews          This review is from: Texas Instruments TI-89 Titanium Graphing Calculator - Battery Powered - 1" x 3.5" x 7.33" - Black (Office Product) My science and math minded daughter used a loner TI-89 all through her senior year of High School and, after being accepted at a very good engineering collage, asked for one of her own as a graduation gift. My daughter could have asked for another model or brand, but she did research and was set on getting the TI-89. This was most useful for use in her AP Calculus and Physics classes so she checked and found that this would also be among the preferred model in her college classes. This is a seriously complicated device with a large learning curve and is likely more calculator than most people will ever need, but for those that do need these functions this is likely the right choice. I have only used it once or twice out of desperation and was able to navigate the basic functions. Highly Recommended! These are listed several different times on Amazon so it might pay to compare.

This review is from: Texas Instruments TI-89 Titanium Graphing Calculator - Battery Powered - 1" x 3.5" x 7.33" - Black (Office Product) I haven't used the newer TI model...but if it doesn't do what the TI-89 does plus more then don't buy it. This TI-89 is like a mini-Matlab. I can design programs that act similar to electronic components and graph them so that I can get a feel at how to work with those electronic components before they arrive. By the way, for those who say that it's better to do math by yourself and without using a calculator...wait till you take a class in controls and then practice multiplying a 10x10 matrix by another 10x10 matrix, and then finding the canonical form of the result on paper and during a test. GOOD LUCK.

This review is from: Texas Instruments TI-89 Titanium Graphing Calculator - Battery Powered - 1" x 3.5" x 7.33" - Black (Office Product) I love the product, however, the description said it came with batteries... which I guess is cool, but they were dead. Might have checked that before shipping/ packaged them separately? Otherwise the product shipped very quickly and in great condition!
