Post Date : Nov 04, 2011 06:30:06 | N/A

Amazon.com Product Description With more power than most of us had in our PCs less than 20 years ago, the TI-92 Plus graphing calculator is the machine of choice for students and engineers both at the desk and on the go. It comes with over 500 KB of memory and software for working through algebra and other mathematic problems quickly and easily.

With the TI Graph Link accessory (not included), you can connect to computers and even download software upgrades. Solve linear and nonlinear equations, use the Pretty Print feature to see equations in textbook format, and work with 3-D surface graphs in real time. The QWERTY keyboard is rugged and easy to use, the 128 x 240 screen is easy on the eyes, and the calculator comes with a durable shell to protect its face when you're traveling or in the field. Additional accessories can turn the TI-92 into a mobile data-collection station, but it's just as useful at home.

Students beware: Some professors and teachers discourage, or even ban the use of calculators like the TI-92 in their classes, so make sure it's OK before you buy. Once you're set, the manual is clear and straightforward--you'll be programming in no time. Ultrageeks will love the assembly-language option, but the rest of us can get by just fine with the regular interface. The old timers might still cling to their slide rules, but anyone who needs a calculator for school or work can see why the Texas Instruments TI-92 is so popular: Its versatility, power, and portability give you the number-crunching power of a computer no matter where you are. --Rob Lightner

The Top 6 Calculator Apps For the iPhone

!±8± The Top 6 Calculator Apps For the iPhone

Our recent article on the top 6 calculator apps for Android was a big hit, and since then we've been getting search inquiries about iOS. You asked for it, and we are delivering. We've searched out Apple's app store for our favorite 6 calculator apps for the iPhone and iPod touch. Since there was a wide disparity in cost of apps, we set the ground rule that we were searching for apps that cost less than . In fact, this list turned out to be our favorite 6 iPhone calculator apps for under .

#1 Graphing Calculator+ by xNeat.com

Graphing Calculator+ is our pick for the best all around iPhone calculator app. It greatest strength is that it does so many different things well. A switch button takes you easily between the calculators different modes. Those modes are graphing, scientific, handwriting, a polynomial calculator, and linear equations calculator. There's still room for improvement. In particular, we wish the scientific calculator had fractions, and that the grapher had trace. But the app is simple and powerful, and the fact that it automatically finds max, min, intercepts, and intersection points pretty much makes up for the lack of trace.

Pros: Handwriting support, graphing scientific, quadratic and cubic solver, systems of linear equations

Cons: Handwriting mode not always accurate, decimals only

Cost: .99

#2 Graphicus by Serafim Chekalkin

We are huge fans of Graphicus. If only every graphing calculator were this easy to use. No need to read the user manual here, just jump right in. Graphicus brings you almost all the information you could want about Cartesian, polar, and parametrics graphs in an incredibly elegant interface. Trace, extrema, inflection points, tangent lines are all readily available with a few taps of your finger. On the downside, there is no simple scientific calculator. It's also a minor bummer that there's no 3D in an app that's 100% focused on graphing, but there's only one app on this list that has 3D.

Pros: Offers everything graphical, intercepts, trace, inflection points, max/min, complete

Cons: Just a grapher

Cost: .99

#3 Symbolic Calculator by Janos Barkai

If you need a CAS for your iPhone, this is the app for you. For those who have used a TI-89, you'll feel right at home with with Symbolic Calculator. The focus of this app is it's computer algebra system, and the interface is pretty easy to use for those familiar with Texas Instrument's CAS calculators. If you're new to CAS's, just tap the question mark next to a given command, and an example will pop up demonstrating how to use the syntax appropriately. You can also use this app to graph, although it feels a little counter-intuitive until you get the hang of it, and the graphing features are simplistic compared to some of the other apps on this list.

Pros: For a CAS, simple to use, offers example input for each

Cons: Graphing could be nicer, mathprint only after inputting

Cost: $.99

#4 Graph It by Tezmo

Another excellent grapher is Graph It. This is also full featured grapher, which offers the ability to trace, find intercepts, and roots, as well as graph derivatives and integrals. It also offers a full scientific calculator with two-line display. The user interface is ok, but might take some getting used to for some users, particularly for the scientific calculator mode.

Pros: Full featured grapher, also a full scientific calculator

Cons: UI takes a little getting used to

Cost: $.99

#5 Quick graph by Columbiamug

For those in need of a 3D graphing app, Quick Graph is the way to go. There are other positives here too such as a strong user interface, simple to use polar coordinates,and a good 2D graphing interface. Screen caps are another built in feature. The real selling point, though, is the 3D, which is well rendered and even accepts cylindrical and spherical coordinates. It is possible to use this app as a scientific calculator, but the interface feels a little strange.

Pros: Polar and 3D, screen caps of graphs

Cons: No trace features, don't feel designed for non-graphing calculation

Cost: Free

#6 Powerone LE by Infinity Softworks

Not everyone is looking for a fancy grapher. For those looking for a more standard scientific calculator, Powerone LE fits the bill. It's got a very intuitive interface that you'll pick up right away. Powereone also features unit conversion and a currency converter that stays current to international currency exchange rates. Additionally, its got a simple statistics calculator that finds the mean of a series of numbers. It could be better if the scientific features used a two-line interface.

Pros: Easy to use, nice UI, currency/unit converter, stays current, simple statistical analysis

Cons: One line calculation, no graphing

Cost: Free with option to upgrade to more powerful version for .99

Five Golden Rules For Adding Polynomials

!±8± Five Golden Rules For Adding Polynomials

Golden rules are the ones that actually apply. You want to keep these things in mind and not forget them. Like stars to steer by, they are permanent markers to guide us and keep us moving in the right direction.

Whatever task you undertake, whatever goal you aspire to, you'll encounter Golden Rules to show you how, you just need to find them.

So let's get started with the 5 best ones for adding polynomials.

Golden Rule # 1, Add Like Terms. The reasoning for doing that this way is just as you add numbers together you can group like polynomials.. Remember, when you see something like 3x + 2y + 5x you can simplify by adding the like numbers together. So the equation becomes 8x + 2y.

Golden Rule # 2, Stack Vertically If You Need To. It will be best to handle this carefully because any miscalculation at the beginning will lead to an error at the end. Take into account that you can rewrite the numbers one on top of the other in the traditional way of adding numbers to make sure you get it right. Sure 3+5 is a piece of cake but if you end up with something like 1,357x + 769x + 6,892x it's best to stack them vertically..

Golden Rule # 3, Separate Your Degrees Of X. There are good reasons you'll want to do that. Among them are that these groups can not be added together. x is very different from x squared.

Golden Rule # 4, Don't be put off by lots of polynomials. There are various ways to do this, including just dealing with one group at a time. You may have 3 or 4 different groups but that's ok. Just add up one group at a time separately.

Golden Rule # 5, If at first you don't succeed try and try again. This may include asking for help if you do not know what you are doing wrong. It is important because doing so helps you to move forward and not get stuck at a single problem.

Follow these rules to adding polynomials and you will probably find life easier for you, your progress rapid as well as your successes more frequent.

The history of computers

!±8± The history of computers

There was a moment in history when the simple arithmetic was compulsory at school. As technology, new discoveries are rapidly converted, as we used traditional methods. One of these great inventions was the pocket calculator. Modern computers are different from the old tools of counting. Devices such as the numerical Comptometers abacus was a manual process, full of errors and it was pretty boring. In contrast, modern computers are digital or solar energy and do not require much manualLabor market. They are very inexpensive and come in many sizes and designs. Following seven facts you should know about computers lucky:

In education
1 There was much opposition to the use of computers at school, because it was thought that deprive them of basic arithmetic skills.
2 Some scientific research indicates that insufficient consultation can retain the use of calculators, mathematical thinking that students learn. On the other hand, other disputes,mathematical devices can weaken the basic math skills, or that such use may prevent the learning of important mathematical concepts.

History: The first day
3 The first type of computational tool that was implanted was the abacus. They were from a square piece of wood with beads sliding on wires above and below. The abacus is still used by fishermen and traders in Africa and Asia.
4 The analog computer was the first time in 150 BC. They called him theAntikythera mechanism and the astrolabe. This computing devices have been in Greece.

From 17 to 19 Century
5 Wilhelm Schickard, a German mathematician, the first digital computer in 1623 He is the father of computing known. His design uses techniques that were used in addition to the computing devices of a watch originally called watches.
6 These devices were later by Charles Babbage (rhymes with cabbage) are improved when he invented the mechanical calculator. It 'wascalled the difference engine, because it could be seven numbers from 31 to manipulate.

Presence
7 In the early eighties computer gadgets were a luxury item costs about two weeks to pay. Prices have decreased the cost of building materials for these devices has become less expensive and more accessible.
Today it is difficult for producers to profit from selling a good computer to go it alone. As a result, companies must sell unique competitive strategies for IT equipment. Now you canGet it as a double element of mouse pads, pens, rulers, and almost everything you can imagine.
