Graphing Calculator - scientific calculator, calculator


If you are a high school student, then this calculator is for you. It has everything you need, for algebra, precalculus, and calculus. The good thing about the 83+ is that it is upgradable, so the need for a new calculator doesn't arise, every few years. Purchasing a graph-link can add on a TREMENDOUS amount of programs to use for Physics, Geometry, and even 3D-Graphs, (previously only on the ti-89 and up). If you are in High School, do NOT get the ti-92 or ti-89, because they will probably be banned from standardized tests, and high math classes, so ask your math teacher, because they are too hard to use and understand. Also, these 2 calculators are aimed for more college-level students, so if you are in college, try the ti-89. But in every case, a ti-83+ is ideal! Texas Instruments TI-83 Plus Graphing Calculator

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. The manual included with the calculator is superb. It goes into detail on every single option the calculator supports. Every section includes a Quick Start tutorial that provides an practical example covering many of the chapter's topics. Learning to program in TI-BASIC, the programming language of the calculator is possible through reading the entire manual and following the examples.The TI Graph Link cable is the interface between a computer (PC or Mac) and any TI Calculator with a link port. It comes in several variations depending on what kind of computer it will be hooked to. The cable is not included with the calculator, but can be purchased as an option. The TI-83+ Silver Edition includes a Black Link cable for Windows PCs.When the TI-83+ is outgrown, upgrading the TI-89 will require little work for anyone who has gained experience with TI's entry level graphing calculator. The TI-89 has the capability to do Calculus and 3-Dimensional graphs primarily.Overall, the 83+ is an excellent choice for anyone taking an Algebra course or any math class above that. The calculator does basic arithmetic, graphic, statistics, matrices, and a variety of other mathematical operations.

If you are thinking of using this calculator for Algebra, Geometry, basically any straight math, especially Calculus, DON'T. That is not to say it won't work, just that there are better things out there, namely the TI-89. The 89 is somewhat more expensive, but, in my opinion and experience, it is far superior for these applications. A few reasons: easier to get the results from previous entries, support for derivitives and integrals, and the higher resolution looks better and lets you put more on the screen at one time, as well as allowing more symbols. However, if you are planning on using the calculator for Statistics, get the 83, because, for some unknown reason, the TI engineers declined to put ANY suppport for stats on the 89, but the 83 is great at it. I have owned TI calculators for many years, and I have never experienced any quality or production problems with them and have never had any of them break except when treated REALLY badly, such as having very heavy, blunt objects dropped on the screen, and I do tend to use mine pretty hard.

I don't recommend spending $100 on a calculator if you don't really need it. Being a college student taking a Statistics class, I was forced to buy the TI-83. I am very happy with it and the various things you can do with it. If you do buy the TI-83 (which I recommend), you should definitely purchase the Graph-Link cable to go along with it. The cable allows you to download various programs and even some cool games from the Internet.

The calculator is fine for school use, up through college as long as you're not majoring in math, physics, or something that motivates a top level device (such as the HP4* or TI89). One major benefit with the 83+ is that it's so common that most teachers know how to use it, many classmates will too, and there is tons of apps and info about it online.However, this isn't really why I'm writing here. I want you all to take a good look at many of the reviews. Especially the five-star ones that say "this is the only calculator you'll ever need!!!", "buy now before it gets too expensive!!", "the Ti83+ is everything you'll ever need and more!!" Notice how they are all from anonymous posters, correctly spelled (a dead giveaway) and well articulated? I swear it breaks my heart that these type of reviews from "users" can't be trusted anymore. It's a fact that resellers and manufacturers actually pay people to write up their products on web boards and commerce sites such as Amazon.Don't trust the ratings or the reviews here. For a proper evaluation, look at the technical magazines that review gadgets, and talk to teachers and classmates instead. - Texas Instruments - Scientific Calculator - Ti-83 - Calculator'
