Texas Instruments Voyage 200 Calculator

HP 48GX comes with a very good equation library. Operation is OK. Not very difficult to learn. Plug-in hardware card is a plus because you won't delete purchased software accidently. Overall, HP 48GX is good but is a little bit old in this modern world.

HP 49G has no equation library. Very difficult to learn and use. Insufficient of manuals, books, and resources. Calculation and graphing are often slower than Voyage 200 for the same problems. The answers to polynomial sometimes look like 0.9999998 but the Voyage 200 gives 1. Some people say HP 49G is the most powerful graphing calculator in the world. As an owner, I would say I don't know. Be aware, HP discontinued their research and development of graphing calculators sometime ago.

TI Voyage 200 is the best. Bigger and better resolution viewer screen. Computer-like keyborad saves your time and efforts that compares to ALPHA ALPHA *****. The keyboard layout also avoids mistakes. Comes with many pre-loaded applications and you can download and transfer more by yourself. Very easy to learn, I did not spend too much effort and feel I can handle this calculator. Plenty of instruction manuals, books, and resources that are compatible to TI 92 Plus and TI-89. It is a pleasure to own and use Voyage 200.

If anyone shows me a calculator who can take more than the 500th power of 2 without scientific notation and rounding -whole number displayed - i will buy that calculator.And the Voyage can pass that, depends on memory available. This thing insane to say the least. Do not buy it unless you are a math or physics or related major. Its over kill for trig or algebra. This thing does miracle in my labs for both chem and physics; and in multivariable calculus and differential equations and linear algebra courses it will give you what no book can: answers to every problem. It is so easy to check yourself with this. Thats why its called PLT- Personal Learning Tool. It has everything. The fact that it is a TI and succesor to the 92 Plus speaks for itself. Any HP is a spec of dust compared to this.
I should point out that the Voyage 200 is an upgrade on the 92 plus. Thats why theres no printed manual. Uses same manual as TI 89. But if you go to [websit]you will find alot of stuff on using it.

Recently received my Voyage 200, and am very pleased with the unit itself. As others have commented, the lack of a decent printed manual is a drawback.

Knowing that the TI-89 Titanium is functionally almost identical to the Voyage 200, I called Texas Instruments and ordered a TI-89 manual. Customer service was very friendly, the manual was cheap ($4.95 + s/h), and it arrived quickly.

TI really should package this manual with the Voyage 200, and maybe they'll start doing it in the future. In the meantime, if you're getting a Voyage 200, just order an 89 manual from TI.

I must confess that I own the TI-92 Plus, which lacks the on screen icons. However, I understand that they are otherwise the same. I own both the TI 83 and the TI-89, and this is far better.The 89 requires the Alpha key to enter text, a real pain. Plus, the 89 has 2-3 color codes per key, making it hard to read. The 92-Plus, and the 200 Voyager, eliminate that hassle for ease of entry and use. It is true that it is much larger, but so what? I have used it to actually try to learn math, and it has been very rewarding for me, eliminating drudgery. One other note of interest: this CAS program was originally written by the guys who wrote the Derive math program, a fabulous math tool. Texas Instruments purchased the company and now uses it in the TI series of calculators. Highly, highly, recommended.
