Texas Instruments TI-89 Titanium Graphing Calculator

This is the most powerful scientific calculator in its class. If you’re majoring in Engineering, or plan to major it, then you must get this one (or regular Ti-89) If you buy anything else for cheaper price, you’ll have to spend $150 more to get this later anyway. (like me) However if your Math class will end up in Calculus or Algebra(i.e. if you’re not going to learn Diff. equation or harder), you don’t really need this, you will just waste extra $70 for the features that you will never use (or features that aren’t allowed to use in exam) So think logically. It’s really cool looking calculator and it got best software/hardware in the world. But if one is going to use it for simple graphic or solving polynomial equations, then it’s really like simulating windows and playing Doom3 on NEC Earth Simulator..Used Ti-83 will do as good for those.

I have owned the TI 82 and TI 83S Silver Plus before this. TheTI 84 is another wonderful product from Texas Instruments for the student in high School or College student. Any complaints about speed is irrelevant. I personally found the TI 84 very easy to read, fast, nice case-I like it better the TI 83 Silver case-and it included some programs that were not on the TI 83. It is supposed to have other stuff that the TI 83 did not have but I did not notice this. This is because I bought it to assist me in Algebra, trig and etc. For the money it is a great investment and a very useful tool. I will say that one area I noticed a great difference in was viewing the window. For me, (and I wear bi-focals) the TI 84 was noticeable in its clearer image and etc. Hope this is helpful.

Texas Instruments TI86 Graphing Calculator

If you are involved with heavy mathematical calculations, you will find that there is nothing better to have at your side, than a trusty TI-86. With this extraordinary calculator you can literally do anything from statistical to calculus work, and even work in the sciences. The interface is simple to learn (speaking in a graphing calculator sense), and the manner in which things are done on this calculator is so much easier than on the older TI-85.

If you need to know what points are in a function, enter the function into the graph, and select table… Voila! In nice graphical format TI-86 will provide you with an x,y table with all points you select! Its that easy… TI-86 also does an extraordinary job with parametric equations!

I have used the TI-85, and actually was looking for one when I bought this calculator. I couldn’t find it anywhere, so I took the plunge and picked up a TI-86… After using it for a semester in university math and sciences classes, I will NEVER go back to the 85!

Texas Instruments TI83 Graphing Calculator

Why would I want a TI 83 you may ask? What about the 89? It’s a higher model, and has more buttons! Yes, that’s exactly it, it has more buttons, and way to many features you won’t use. I have a Ti 83+ (More memory than the origional, but same everything else) and it is great! It has built in Financial Apps, which is a nice addition (and helpful!) compared to the 82 (which it is also compatible with!). But the 89? Even the 85? They take greater than calculus students to even need/use those functions, and they are a much harder to learn calculator. The Calculus teacher at our school says that the 83 will get you all through calculus and most likely beyond college. My calculator, which is really easy to learn, came in handy the first day in Geometry. We had to figure an area of a wierd shape and we only had the co-ordinates, i punched them in, and POW, found the area. If you do get this calculator, a TI-Graph Link is a must, this allows you to download software and updates from TIs website, some software could almost be considered cheating, while others can be games for fun. Unless you want to spend $200 for a TI-92+ (not even allowed by most teachers, it’s so powerful), this is THE calculator for you!  Read More TI Graphing Calculator Reivews >>>

Texas Instruments TI-83-Plus Silver Edition

Texas Instruments produces some of the most popular and well known graphing calculators in the industry. The TI-83 plus can do most any math problem found in Algebra I, Geometry, and even some Algebra II/Trigonometry. The wide screen allows for graphing equations and multi-line functions.

The graphing capabilities of the TI-83+ are a superb choice for Algebra I classes. The ability to automatically find intersections and a variety of other important components of a graph are only key presses away.

The calculator has a powerful matrix editor allowing for easy multiplication, addition, and subtraction of matrices. Division of matrices is not possible. The list editor allows for statistical analysis of data both numerically and graphically. Graphically, the 83+ can plot data in several different formats.

Anyone who is familiar with the BASIC computer language can program the TI-83+ with ease. The calculator supports the use of almost every function through a program. Programs can be typed directly into the calculator, or on a computer. The TI-83+ also supports a special form of programs called Flash Applications. Flash Applications are generally quite complex, and are written in a special language on the computer.  Read More TI Graphing Calculator Reivews >>>

Texas Instruments TI-89 Advanced Graphing Calculator

The TI-89 is an excellent calculator. It has an absolutley HUGEfeature set, and is so advanced that it can basically do most math for you. My favorite features are the CAS (computer algebra system), which can solve a lot of algebraic equations for you, and the factoring function (I dont have to waste time factoring on paper anymore! whoohoo!). My old ti-83+ seems like a slide rule compared to this thing, but the 89 is still quite easy to use. In addition, not only is this calculator great for math, its great for games! There’s a multitude of mathematical programs and games that you can find for free online. . . The only downside to this calculator is that the rich feature set can actually be a problem. A lot of students that use this calculator rely on it too much, and some of them barely understand any of the math that they are supposed to be learning. It is probably for this reason that it and its brother the TI-92 (difference between the TI-89 and TI-92 is the 92′s qwerty keyboard, useless for a calculator in my opinion,and the 89 is smaller) are banned in some colleges, and on some tests, like the ACT’s. If you’ve got the discipline not to rely too much on this fine piece of equipment (if you’re a student), I highly recommend this calculator. But be warned, keep your old calculator around for tests that you can’t use your 89 on, and NEVER rely to much on it.  Read More TI Graphing Calculator Reivews >>>

Texas Instruments Voyage 200 Calculator

The actual calculator itself is stunningly powerful. It is faster than the TI-92, the full keyboard makes it easier to work with than the TI-89, and the ability to solve, factor, work with imaginary numbers, give exact answers, as well as do all of these things symbolically, plus the amazing applications included (a version of Geometer’s sketchpad!), make this the best calculator made by TI.

Just beware that some standardized tests and some teachers will not let you use this calculator.

The biggest drawback is the documentation that is supposed to help you utilize the power of this calculator. There really isn’t any. There’s a short manual that’s included in the box, but it only gives you the broad overview of how to put the batteries in and how to turn it on and off.

To find any information on how to, say, type something in that you want to factor, you have to load up the cd-rom, and hunt around on that thing to find the information you want.
Why don’t they include all of this documentation along with the calculator in an actual book form? (Okay, so I know the answer to that – it saves money for them.)  Read More TI Graphing Calculator Reivews >>>
