What is a Graphing Calculator
Calculator, an electronic device to perform calculations, is known to us from childhood. Some calculators allow us not only perform simple math operations, but also derive complex formulas and perform programming. But what if you need to immediately draw a graph for the obtained values? graphing calculators can help you solve the problem. graphing calculators are almost mathematical computers with graphic screens. Not only do they help you calculate, but also show the results in graphs.
As an addition to your graphing calculator we recommend buying a document camera, which helps you optimize your study process. With such a device you are able to visualize (scan) different electronic documents and file content, 3D objects, flow and motion diagrams by outputting them to a display or a TV, interactive board or a projection screen.
What Features to Compare
Choosing a graphing calculator, you first need to pay attention to its Functionality. Best graphing calculators should ideally combine all the necessary functions that will enable its use in various fields of science, such as algebra, trigonometry, geometry, statistics, in the field of business, finance, biology studies, physics, chemistry, calculus and linear algebra, at the same time. Tables and lists modes make it easy to operate with a large number of digits and numbers and perform statistical calculations. It is worth to pay attention to the built-in library of equations and functions where all a user needs to do is to substitute their values. It is better if graphing calculators have the ability to add custom functions — for example, if you lack built-in functions in a calculator, you can always create your own program in such a calculator.
Another important parameter when choosing among graphing calculators is their Specifications. They make a difference to how quickly the device can cope with the tasks. graphing calculators have their own built-in memory where all knowledge database of a device is stored. The best graphing calculators have up to 16 MB of memory. It is good if a calculator has an expandable memory that allows you to improve the functionality. Another important parameter for graphing calculators is the amount of RAM that directly affects performance and speed of calculations. One more virtue the best graphing calculators can impress with is their ability to connect to a computer through a USB port that allows the transfer of files and data between the devices.
graphing calculators feature the ability to display graphs and charts. This implies the importance of such component as a Display. Modern graphing calculators mainly have LCD displays. The best graphing calculators have excellent color LCD displays with more than 65 million vibrant colors. Next, it is important to consider the screen size. The best graphing calculators feature a screen size of about 4 inches. And finally, the most important parameter to assess the quality of a display is its screen resolution. This directly affects the quality and graininess of the image itself and how precise the graphing will be, especially in 3D visualization and operations with three-dimensional models.
A Battery plays an important role in the work of graphing calculators. Manufacturers tend to use AA and AAA batteries in their devices. Basically, it is convenient as at their discharge, you can simply replace the batteries. On average, these batteries will be enough for about 140 hours of autonomous work. But, many companies have developed their own types of batteries that can be recharged when needed. The work of such built-in rechargeable batteries can last up to two weeks under normal use of the calculator.

HP 35s Scientific Calculator
The Choice is Yours
The HP 35s model is one of the few graphing calculators, which enables you to choose between two popular data entry systems, namely the reverse Polish notation (RPN) and the algebraic logic. The reverse Polish notation (RPN) is a notation of mathematical and logical expressions, in which operands are placed before operator symbols. This representation type known as reverse Polish notation is also called a reverse bracket-free notation (RBN), postfix notation, Lukasiewicz’s bracket-free notation. As for the algebraic logic, it is simpler to implement as it requires only two operation registers for two last operands and saving the last entered operation. This kind of notation is quite convenient for performing simple calculations, for example in the instances when a user hasn't prepared the whole calculations sequence beforehand but performs all calculations on the fly instead; with that, a user is interested only in the current operation and its results. This functionality shows that this versatile HP 35s graphing calculator that supports the reverse Polish notations and programming functionality provides comfort and ease of use. This model is one of the best graphing calculations for engineers, surveyors, students, research assistants and health professionals.
Paying Tribute to Classics
Today very few people know that HP company had no connection to the production of personal computers up to the middle sixties. The first calculating device by this company was the НР 2116A mini-computer. The price of this behemoth of a device was $50 000. Interestingly enough, this computer is the largest electromechanical device ever manufactured by the company. Initially, the НР 2116A computer was designed for the domestic wants satisfaction but afterward it was decided to establish a batch production. Getting back to the topic, the first programmable calculating unit in the world was produced by HP in far 1968 and was named HP 9100A. The maximum configuration of HP 9100A was being sold at $4 900. This computer was distinguishable for offering its users a few very elegant engineering solutions (for example, the computer was able to save the last entered digits on an emergency power off) and soon gained popularity. After a few years, in 1972, the world’s first scientific handheld calculator the HP-35 was produced. At that time this calculator was innovative and the first truly compact computing device. Subsequently, the HP-35 gained a recognition as one of the most important milestones in the history of computers development. That is why in 2007 the НР company decided to launch the production of HP-35s anniversary model with a vintage design to celebrate the 35th anniversary of the legendary HP-35 model.
