subject: Functions Found Present In A Graphing Calculator [print this page] A graphing calculator can be a very helpful instrument in many forms of mathematics. Its higher functions make it very different from most calculators and make it much more useful. Although there are varying ones to choose from, all of them share certain standard abilities.
Extremely useful is the fact that data entered does not disappear like a standard calculator. More like a computer, the user can delete, navigate through, and re-enter parts of an equation without having to start over if a mistake is made. Not only can the whole equation be seen at once, but multiple equations can remain on the screen at once unless deleted by the user.
These calculators also have the ability to save functions and formulas into their hard drives. This allows users to simply bring up the necessary equation and plug in the needed numeric values as opposed to re-entering long formulas every time one needs to be used.
Of course, it is to be expected that charts, graphs, and lines can also be used. Instead of hand writing graphs or data points and not using the calculator until the final equation is found, the entire thing can be done at once without ever having to do any of it on paper or by hand.
Further, bluetooth capability, USB ports, or other ways of transfer allow multiple users to sync to each other and share stored data with each other or download information from each other. It is also possible to connect to another external device such as a computer or projector to allow multiple people to see data at one time.
It is obvious that a graphing calculator is a very useful tool, especially to those who intend to spend great amounts of time on mathematics. Its higher level functions are able to bypass many of the hassles and inability of standard calculators to perform certain tasks, giving it great worth.
