Texas Instruments Voyage 200 Graphic Calculator

This calculator can do it all. If you need to graph any 2d or 3d functions, it can do it. If you need to complete complex derivates or intergrals, no problem. This is a great tool for anyone looking to complete a degree in mathematics or engineering! It is very simple to use but can complete the most complex functions. It is a great buy for the money and even though the TI-92 can be found for less money, the voyage 200 is the new model, and will stay relavent and up to date for quite a long time.

I love the size of the screen on the calculator!! This calculator is perfect for derivatives, implicit functions, limits, etc. In other words this is the best for advance math courses such as CALCULUS! You have to get use to including the closed parentheses on every equations you use parentheses. It is neat you can program the answers to result the "exact answer, APPROXIMATE, or AUTO"! For example when calculating the square root of (8), the answer results in 2 * sqrt(2) for exact answer or 2.82843 for an approximate answer; which is the normal result on most other calculators such as TI-83. The clarity of the screen is great. It is neat that the fractions appear like the way you write on paper, expecially when you store your eqation into y= for graphing!!! Another thing you can do that is very neat is use split screen mode where you can view one thing and another thing side-by-side or top-bottom. For example, you can choose to view the home screen on the left side and view the graph on the other half of the screen.

The disadvantage are that it is difficult to use the voyage 200 without using both hands. Also compared to the calculators below TI-89 (TI-83,84,86); the TI 89, 92, and voyage lose the button having (x^2) and just has the (^) key. This key was very useful, but on the TI 89, 92, and voyage, you have press the carrot key for every power degree. For example for x^2 you press the letter x then press ^ lastly 2. Its not a big deal, but the button was very useful. The feature could have been included in the math catagory on the calculator, but for some reason its not. All together, this calculator is the ultimate calculator!

The calculator is wonderful..The transaction went well and we were very happy with the outcome. Thank you.

Clearly a powerful calculator capable of active (you can rotate them) 3d graphs. Only thing to be careful of is it doesn't come with a printed manual that covers the use of its many programs and features. This comes on a cd, which can only be easily browsed in windows, so any linux users be ready to dig through the cd to find the information you need.

The TI Voyage 200 is just pecfect for the student in science, math or enginnering. I spent for years in university using this and I can tell you it's marvellous.
You can upgrade, pre-program any formulas or equations.
Finally, you can download games to your TI and play them in the boring courses.

I bought this calucotr for school because it was a specific one they wanted for my math class. it is easy to use & suprisingly affordable, resonably priced compared to what I found in retailers online. Overall, Its a great graphing calculator to work with. No complaint I real happy with this purchase.

thanks...the calculator is excellent....inclued everything. and so fast, thanks heather, you are a great seller.

Good service, the item received was in good shape. Thanx ++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Its a fabulous gadget for college, all the work is easy in calculus sudjets.

I use along two semesters and don't have any problems to use it.

This is an amazing calculator. I use it in my engineering courses, my computer programming courses, and all my math courses. I have used this calculator for matrices, to differentiating algorithms, to plotting 3D graph. It is the most powerful, yet user friendly calculator I have ever used. I compare this calculator to programs such as MathCad and MatLab.
To put it short, I place this calculator as a necessity these days!!!! The conversions from polar to rectangular to normal are, in itself, worth every penny I paid for this item!!!!

I bought the TI-200 voyage a few weeks ago. I'm very happy about this item because it was like new. I bougth this item to sold it, I think I get a good price for it.
