DOWNGRADE

I'm quite sure this is a very great calculator, but it doesnt help me at all, maybe its to complex for my grade level (10th. I'm going to have to downgrade because its a waste of my time.

I know I say experience for fours...

Strengths: AP Calculus, AP Physics, and Engineering Capabilities.

Weakness: Software (TI-Connect) to put programs on the calculator could be easier to use for those not computer oriented.

I know I say experience for fours days (I have had my own for four days), but I have used the calculator for about a year, as I have used my friend's.

For a few years, I had the TI-86, and for graphing purposes and playing games of course, this was all that I needed to do. But when I went into Calculus, graphing alone was not enough. The TI-89 Titanium performs integrals and derivatives, and with Calculus Tool (program that you can download from the TI website) you can even do implicit differentiation. Also, with another download it is possible to do volumes by disks and washers.

Now that we have put some very helpful calculus function behind, it is a very helpful physics and engineering tool. From 34 physics (including circuits) constants (from -1.602 X 10 to the 23 to Avogadro's Number) to graphing analysis of buildings for civil engineers, this calculator can do it all.

The interface of the calculator is the best. I was continually clinging onto the TI-86 through the calculus year until finally me friends convinced me otherwise right before the exam. But even more convincing was just how the calculator worked. Instead of getting a large decimal for the cos of Pi/2, you get real answers like (radical 2) /2. (The format looks like it would in a math text book.) Also amazing about it is the simplicity to use it. The manual is a little less than 300 pages, but the calculator does so many functions that if you are looking for specific functions, then you can simply skip many sections that may not be of use to you (after all, we are all not nuclear physicists!).

One difference between the TI-89 and TI-89 Titanium is memory. The Titanium holds upwards of 500KB or ram, as the TI site says, which is much more than the just the 89. This way, you can download a lot more physics, math, and game programs in case you ever get bored in History 101 (for the most games, go to ticalc.org). And this brings us to the transfer ability. The Titanium, unlike the regular 89, has a USB port for connectivity, so you do not have to use those old serial ports anymore. The calculator comes with the USB cable for connecting it to your computer along with a USB unit-to-unit USB cable link directly to other Titaniums. Concerning the transfer process from computer to Calculator, the software (it comes with it) is easy to setup, but can be difficult to use if you do not know whether to archive the file to you r calculator or send it as ram. But even before that, sometimes the program fails to communicate with the calculator so you may have to unplug it and plug it in again before it will work completely. But again, if you can find someone that already has all of the programs, you can just use the unit-to-unit cable and get the programs from them.

Therefore, if you are looking for the integral of the ln (2x) + e to the 2x +25x or just plain multiplication, the TI-89 Titanium can do it all quickly ans easily, providing non decimal answers unless you want it to (love that feature). With the TI-89 Titanium you are control!

After using a TI-83 Plus...

Strengths: Powerful, fast, lots of memory, includes USB cable

Weakness: the sliding cover is very very hard to slide off

After using a TI-83 Plus calculator for the last 5 years, I decided to upgrade to the TI-89 Titanium. This calculator is unbelievable in its features and power. First of all, it is more suited for advanced math, such as calculus and beyond. If you are a student in a class below calculus or don't do any work that involves such advanced math, then save your money and buy a TI-84 instead. This...

it's worth the price

Strengths: Great capabilities

Weakness: if you have never used a grahing calculator, be prepared to spend a lot time reading the manual.

Makes math, physics, chemistry classes much easier. Many people in class (including the instructor)will have this calculator. It allows you to focus on the concepts not the math details.

Strengths: Tons of memory, Soo...

Strengths: Refer to Comment:

Weakness: Refer to Comment:

Strengths:
Tons of memory, Soo many features, makes math soo easy that they don't even allow them on the ACT test. Which is no big deal for me because where I live almost every college use SAT. California. This calculator does soo mcuh, from 3d graphing to simplifying, adding, and subtracting Ration expressions. The list is endless. This is by far the best calculator out there for the price. I'm soo happy I got this over a Ti-84. I was close to purchasing a Ti-84 over a Ti-89 only because i've used them before and didn't want to have to relearn how to use a calculator. The calculator was extremely easy to learn how to do. Within one week I learned how to do almost all basic functions. I even got games for it, which really isn't necessary. I'm currently in Algebra II in High School and this calculator makes my life soo much more easier. We're currently working on Rational Expressions and simplifying them, my teacher was explaining how to do a problem on the board for about 30 minutes to the others in the class while I was sitting down plugging in the problem and got it in less than a minute. Battery-life on this calculator is pretty good as well. I haven't changed them in 4 months, I use this almost every day for about an hour. It also comes with a Unit-to-Computer cable and a Unit-to-Unit cable(which I never use since I'm the only person in my school to have a Ti-89 Titanium).

Weaknesses:
At first the cover was extremely extremely difficult to remove. But over time it began to wear itself down and now it's somewhat too easy to come off. The other bad thing is that for College acceptance test, this calculator is prohibited on the ACT test, which isn't a problem for me anyways since I live in California and almost every college out here uses SAT. Besides the problem with the cover this calculator is perfect. The only thing that they could do to this thing to make it even better is give it a color screen which isn't even needed. Some may say the price, but this calculator was worth every penny.
