The benefits of Graphing calculators

Graphing Calculators have assisted professional engineers and scientists since their invention. By the mid 80's calculators had replaced abacuses in the pockets of professionals, offering transportable and easy computation and manipulation of data.

Many students don't realize how beneficial a calculator is in math courses. Graphing calculators are recommended for math courses from pre-algebra onward, and college programs involving physics, calculus or statistics often require a graphing calculator. Successful high schools are offering class sets or requiring students to purchase a good quality calculator, so that students can familiarize themselves with the tool. Students can use the easy computation and manipulation of a quality calculator during their Sat, Act, or AP placement tests to enhance their calculus abilities.

Graphing calculators are similar to a laptop computer in many aspects, but are much lighter and less expensive. Calculators with graphing capapbility hold many types of data in the on board memory, including gathered statistics, games, notes, and mathematical functions. Manufacturers offer free software that can be used on the calculators they produce, from games programs to advanced tools that enhance calculus abilities. Calculators are equipped with a larger screen than a standard calculator that users to see a visual representation of the work, and they display charts and graphs of data that users can easily manipulate. Calculator data can be saved to other graphing calculators or input in computer programs. Calculators perform complex mathematical functions that standard laptops don't without additional software.

Good calculators are an invaluable tool for today's students because they offer easy computation and manipulation of data, a significantly wider range of functions than standard calculators, and are less expensive than a laptop. Users can define their own formulas and inputs that enhance the calculator with increased calculus abilities, making them a necessary tool for college-bound students.

NLVM's Free Online Graphing Calculator

!±8± NLVM's Free Online Graphing Calculator

It's easy to find interactive graphing calculators websites, but finding a free, easy to use graphing calculator applet that's not buggy is more of a challenge. One of the best is hosted at Utah State University's NLVM site, the National Library of Virtual Manipulatives. If you're not familiar with it, NLVM is an extensive collection of interactive applets for students and teachers. You'll find not shortage of interesting puzzles and games there, but this time we wanted to highlight their "grapher" applet.

What sets apart the NLVM grapher is its simple to use, yet powerful interface. An easy to use menu at the top of the screen allows for fractions, exponents, square roots, and absolute values, and they can all be inputted just as they appear in a textbook. There's very little clutter on the screen to intimidate users.

There are surprisingly powerful options for a Java based calculator. Of course, there is a simple trace feature, which utilizes a slider bar. There are three additional tabs for users to choose from, parameters, window, and functions.

Parameters allows the user to insert up to three parameters into the equation that can be manipulated with a slider bar. If you are interested in examining translations, this is a very powerful feature since the graph adjusts in real time.

Not surprisingly, the window tab give the user the option to adjust the graph view. Fortunately, it is also possible to zoom by simply using the mouse to select a region to view.

The functions tab gives the user the ability to input up to three functions. One of the really nice features here is that composite functions are supported (although inverse functions are not). Other advanced features offer the ability to choose each functions color and restrict domains.

The applet doesn't contain all the functionality of a high end graphing calculator handheld, but that's not really the point. Whether you're a student using it to try out graphing for the first time or a teacher incorporating it into your lesson, it's a simple and reliable solution. NLVM's grapher is one of the best online graphing calculators available today.

The Best Calculator - Texas Instruments TI-89 Titanium Graphing Calculator

!±8± The Best Calculator - Texas Instruments TI-89 Titanium Graphing Calculator

A graphing calculator is an electronic device used in performing mathematical calculations such as solving equations and plotting graphs. It is programmable, allowing the user to create customized programs for education and scientific/engineering applications.

A graphing calculator can provide several calculations and text lines at the same time. Some have color displays, while others include 3D graphing. The TI-89 Titanium is one of the model graphing calculators popularly used today.

The TI-89 Titanium has a powerful computer algebra system developed by Texas Instruments. This allows the manipulation of symbolic algebraic expressions, where in, it solves the equation in terms of variables.

Hence, the TI-89 Titanium is a replacement of the TI 89 which was released during the summer of 2004. It has four times the ability of the TI 89, especially with regards to its flash memory. More Apps, programs and data are being stored. Thus, the TI-89 Titanium is necessarily a Voyage 200 without an integrated keyboard.

Features:

- TI-89 Titanium handles algebra, calculus, matrices, and statistical functions.
- RAM: 188 KB
- Flash Memory: 2.7 MB
- Pixel Display: 100 by 160 large pixels (split screen view)
- Power: 4 AAA Silver Oxide batteries
- Units: More than 100 in 28 categories
- Stored constants: 20
- 255 symbols in the character set (Greek, system, and international characters).
- Real time rotation- 3D surfaces.
- File sharing with the used of USB on-the-go technology.
- Optional assembly language programming
- Has a 3-D rotation and contour plots.
- Active Calculator Home history screen - can hold up to 99 previous entries for deep recalling purposes.
- Graph mode can stored up to 99 equations for each mode.
- Real and complex numeric results.

Cheap TI 83 Graphing Calculator

!±8± Cheap TI 83 Graphing Calculator

I'd been searching for a cheap TI 83 graphing calculator for a while now. Since they can be pretty expensive, I thought I'd share what I've found during my research.

What is a graphing calculator?
It's a brilliant piece of technology that can make life so much easier for math and science students. It's used mostly for higher level math - trigonometry and calculus - and allows you to work with several equations simultaneously. You can enter any equation and see it graphed - it makes the task of graphing really difficult equations quick and easy. The LCD screen allows you to track your calculations by letting you see all of the numbers you enter.

Many of these calculators, apart from solving equations and being able to store and analyze up to ten matrices together with data storage in lists of nearly 1000 elements per list also have the facility for playing games. The TI-83 Plus is one of the best calculators for this function - with thousands of games you can download online for free. You can also actually program simple games on it, and in fact it's a great introduction to computer programming if you're interested in going into that. Compared to the more expensive models, this one is much easier to use, and if you can find it at a good price, it's excellent value for money.

Finding a cheap TI-83
Although you can get more advanced models, the TI-83 has all the functionality needed for calculus, trig, statistics and more. However, if you're needing a graphing calculator for physics or chemistry you'll need a more advanced version like the TI-89 instead. Good quality graphing calculators are expensive, costing up to 0, but you can get cheap ones if you shop around. Instead of paying the regular retail price, you can find a cheap TI 83 graphing calculator online if you know where to look.
