Digital camera reviews of Texas Instruments TI-83 Plus Graphing Calculator
Digital camera Review: A Highly Useful Calculator
Summary: 5 Stars
I bought the TI-83 PLUS during my high school freshmen year. I bought it because we needed for Geometry. As a sophmore, I found this calculator to be a very useful tool as I continue to use it! I use it for algebra II AND chemistry -- plus, like they said, it's upgradable. Of course, I don't know ALL the functions of this calculator, but it's very useful nevertheless. It has a great keypad, a ton of functions, and it's easy to change modes. The TI-83 PLUS is incomparable to an ordinary scientific calculator -- it is SO much more! I think the TI-83 PLUS is the best buy, since it's upgradable and all. It's better than the the regular TI-83 and a better buy (since it's only a few bucks more). Even the overall look of it is different -- The TI-83 PLUS is pretty slim, in my opinion and its screen is better than the TI-83 screen. Overall, this is one of the best graphing calculators out there!Digital camera Review: A Review From a Trig Student
Summary: 5 Stars
This calculator is the best!!! Its best feature is that it is easy to use. My high school, and alot of others, are still using the TI-82, so when you learn to use the calculator, you have to learn on your own. But simce the 83+ is really similar to the 82, learning the functions is easy. Its fast and easy, and the pixels are easy to read. It was great on the PSAT. Its also alot cheaper than the 89 or 92, and performs all the functions that you will need up to Calculus and even slightly beyond. I reccomend this calculator to any High School Student in Algebra 2 or higher.Digital camera Review: A TI-83 Plus disaster!

After reading the reviews, I really believed that I had purchased a wonderful product. It was wonderful until it died during a calculus test! My calculator is two months old. Buyer beware on this one!Digital camera Review: A complete friggin joke.
Summary: 1 Stars
Negative 5 stars. Lets be real people, the mere existence of this device is perturbing. It is the one electronic that has evolved absolutely none in 15 years and gone UP in price!! My friend bought one recently in a pinch, he thought it might help him with calculus. I figured it'd have some new chip technology and would graph at a reasonable rate. Both no. So then I downloaded a FREE graphing calculator app on my outdated Android phone. And it's friggin marvelous: instantaneous, intuitive, will do a 3d graph of x=sin(y) (3x faster than the ti does sin(x)) that rotates in full color with ability to pan and zoom on the touchscreen.
I can't even list all the advantages of an android/iPod over the TI's in this space, but what about battery, USB, internet, brightness, 192mb ram.. The TI-83 must be $3 to make by now with it's laughable 32kb!! of ram and 6 mhz processor. This makes my (dated!) phone exactly 88 times as fast with 6000 times the memory. I did that calculation on my phone and if I threw in a sin(x) at the end it would have automatically graphed 88sin(x) for sh!ts and giggles. Then I could zoom out 10 times, take a screenshot, and email it to you, just because I can (in 30 seconds). Hello! Note that even if I didn't opt for a cell plan I could still use wifi. Ahem. Wifi.
Shame on the people who keep this piece of junk in the school systems as a standard. Realistically, a dedicated device of this price today could be phenomenal. Apple should make one. TI is going to (and deserves to) be brutally trounced in the calculator market for this eventually, but in the mean time they're basically restricting learning in schools to be done at a snails pace with minute functionality for a large profit, and for the massive portion bought by the school system, at your expense.
Digital camera Review: A great and extremely useful calculator
Summary: 5 Stars
I am in a 7th grade advanced AlgebraI course and bought this for the class. It never let me down, and according to my teacher I will use it for the next 6 years, all the way until college. It is extremely fast, easy to use, and its several features make it a great choice for anyone. You can also play games on it if you're really bored during a class! Awesome calculator!
