A graphing calculator has become a staple of every math-class. From algebra to advanced calculus, you can find a model that best suits all your needs so that you can use it to its fullest potential. In addition to plotting graphs, drawing and creating complex programs, it has the ability to perform advanced mathematical and scientific tasks. Most of them are ideal for dealing complex matrices, calculus and graphs. Apart from being powerful and capable, these models are more user-friendly and aesthetically pleasing. Similar to that of the scientific models, these come in a variety of capacity levels and designs for matrix calculations. Some of them have approximately close to 500 built-in functions. These are usually powered by batteries and feature different font sizes. Compared to the old-fashioned ones, the newer models come with color display and touchpads. Some of them allow you to link datasets, store notes and also upload pictures to help you understand the mathematical concepts better. With their ergonomic designs, user-friendly buttons and several other functions, these are easy to use. The multiple functions of these enable you to define, analyze, save and present data in a graphical mode. The two basic types of graphing calculators include Computer Algebra System (CAS) and Non Computer Algebra system. CAS can factor, evaluate, integrate, solve and simplify equations all with just the touch of a button. It is a perfect choice for advanced mathematical students and scientific professionals, who utilize the symbolic expressions. Non Computer Algebra System, also known as numerical calculator, performs the basic numerical equations. Some of the standard models feature natural or conventional display, Universal Serial Bus capabilities and 3D graphing capabilities. The features of graphing calculators are considered to be the technical aspects that include RAM, ROM, input styles and the screen resolution. When buying, you can consider the ones with high amount of random-access memory (RAM) as they help in faster calculation and graphic speeds. Most of them have algebraic input method. For example: The Texas Instruments, TI-89 Titanium comes with a built-in computer algebra system which lets you simplify mathematical expressions and equations. Some of them are designed with date and time display information. The active calculator home history of the screen can hold close to 99 previous entries for recall. The USB compatibility allows you to connect them to different devices. Some of the TI models are provided with Impact Resistant Slide Case to protect them from scratches. Some of these calculators are complex and often require documentation to perform specific tasks. For example: The Texas Instruments, TI-84 Plus Silver Edition can be used for standardized tests. This comes with 2D, polar and parametric capabilities that help you solve complex problems with much ease. With auto-off feature, it automatically turns off whenever you are not using the calculator. It also helps you calculate Currency Conversion, Division, Trigonometry, Standard Deviation and Regressions. The TI-Nspire from Texas Instruments is capable of performing multiple tasks and some of them are powered by rechargeable batteries. Through the USB port, you can also transfer important data’s from computer to the calculator. This calculator is ideal for Trigonometry, Geometry, Pre-calculus, Statistic, and so on. With the advent of e-commerce websites, you can buy graphic calculators online. Most of the graphing calculators are made by Hewlett Packard and Texas Instruments.
