Digital camera reviews of Texas Instruments Voyage 200 Calculator
Digital camera Review: Industry leading and remarkably capable for almost decade old technology
Summary: 5 Stars
This graphics calculator is really a small computer. Although the keys are too small for touch-typing, the qwerty keyboard allows an extremely large range of built-in functions to be entered with relative ease. If you don't remember the functions, the calculator provides menu access to the full list.
This calculator can perform both numerical and symbolic calculations, with answers in a mathematically exact form, or numerically rounded if desired. It can evaluate and solve both algebraic and calculus problems. It can graph single or multiple functions simultaneously or individually, where you can choose the type of display format, e.g., line, dot, square, thick, ... to distinguish each function. You can also plot sequences, etc. You can zoom in and out of a graph, reset the range of coordinates, trace the cursor along the curve to read coordinates, calculate maxima and minima, etc.
TI provides ongoing support for this system, and if recent history with the earlier TI-92 and TI-92 Plus predecessor systems is any indication, will continue to do so even when a replacement becomes available.
The Voyage 200 approaches, in many of the most widely used areas, the capabilities of more expensive mathematical software packages available for the PC, e.g., Maple, Mathematica, etc. In areas of overlap, this TI is almost always easier to use, although in less common mathematical domains its capabilities are much more limited or non-existent.
The system's leading position, and the lack of effective competitors is both an attribute and a handicap. The Voyage 200 derives directly from the TI-92, TI's first symbolic calculator, released in the mid-1990s, which was then updated a bit to the TI-92 Plus in 1998. The Voyage 200 is essentially a cosmetic update, with increased flash memory, of the TI-92 Plus. For example, its display is still 240×128 and still monochrome.
Clearly this, essentially decade old, system would benefit from a serious refresh. Display improvements in PDAs, cell phones, and other palmtop devices demonstrate the improved resolution currently available, and the introduction of color would significantly help in the presentation of multiple plots, etc. One hopes that TI management and engineers have already taken a serious look and are soon to release an upgraded system that includes not only the appropriate hardware improvements available for the display, memory, and processor, but extensions in the range of mathematical functions available, as has occurred with competing mathematical software systems.
TI graphing calculators developed with TI's acquisition of Derive mathematical software some years ago. However, when the company announced that as of June 29, 2007 they would no longer sell Derive, apparently development stopped in 2006, there was/is an open question as to what TI's interest and capability will be to move their graphing calculator software forward in the near future.
However, it is hard to fault a system that "got it right" from the start, has an incredible range of mathematical capabilities, is programmable, and allows for internet updates to its operating system and the installation of new applications. In spite of its age, this is still a remarkable industry-leading system that is really a pleasure to use.
Digital camera Review: It works but not in great condition
Summary: 3 Stars
Condition was not as "good" as portrayed. It works but looks a little banged up!Digital camera Review: It's a Wow Calculator, The Thecnical Manual is on a CD to Save Paper
Summary: 5 Stars
I Would disagree if this calculator has print its manual, because is over 2000 pages, and all are in PDF file. Beautiful calculator, very powerful. Bulky but necessary, wish that they could redesign its cover like sliding it. (like the TI-83, 84, 89). Wonderful. Would recommend.Digital camera Review: Just for info.......
Summary: 5 Stars
FWIW
Manuals for the TI-89T and Voyage200 are located (buried) on TI's educational website..... http://education.ti.com/downloads/guidebooks/eng/89ti/
Have a good one,
Digital camera Review: Missing many statistic functions from TI-83
Summary: 4 Stars
Really good calculator, everything works good, and is really really fast for huge functions. As a statistics major, im a bit dissapointed, because this calculator is missing alot of the random functions the ti-83 had. Everything else good, great buy.
