Students and professionals often have a need for a well-designed and crafted graphic scientific calculator for school or office use. With so many on the market, finding the one that does all the calculations you need and is easy to understand and use may take a bit of investigation. However, with the facts to hand, deciding on the right calculator is easy.
About Graphic Scientific Calculators
A graphic scientific calculator is not one particular calculator; it is a classification of certain types of handheld units. Graphic calculators can perform advanced mathematical and scientific tasks in addition to plotting graphs, creating complex programs, and drawing. Examples of graphic calculators include ones manufactured by Texas Instruments, Casio, Sharp and HP. Small hand held calculators quickly and efficiently do calculations that once took hours in a few seconds.
Types of Graphic Calculators
There are two specific types of graphing calculators. Computer Algebra Systems (CAS) calculators manipulate symbolic expressions. Graphic calculators can evaluate, factor, integrate, and solve for roots and simplify equations at the touch of a button. Geared toward advanced mathematical students and scientists who utilise symbolic expressions, the CAS calculator saves hours of computation and minimises errors. With technological advances and the need for more complex computation, the CAS is becoming more standard in schools and business. Non-CAS calculators are numerical calculators that compute basic numerical equations. While both types of calculators have a graphic display screen, complex computation abilities, and instant results, the CAS graphic calculator is the more sophisticated. Occasionally consumers confuse engineering calculators with graphic calculators, but they are not interchangeable.
Features of Graphic Calculators
Features to look for in graphic calculators include the ability to utilise a USB cord for updates and additional programs as well as buttons and symbols that are easy to understand and use. A clear, crisp, and sharp display screen that is visible in bright light as well as darkened lecture halls is also important. Most people also need a long battery life and the ability to charge from mains, but be sure to consider those that are also solar charged.
Comparing Graphic Calculators
When selecting the correct graphic calculator to fit your individual needs it is important to take into consideration how you intend to use it. Consider whether you intend to use your calculator exclusively for graphing or if you need to format and calculate formulas. If the calculator is for high school or university, it may be important to note whether students are able to use the calculator on standardised tests. Also, consider if you can download additional programs as well as whether you can update it. For those who toss the calculator into a backpack, it might be a good idea to look for durability and long life functionality.
