Graphing calculator
From open-encyclopedia.com - the free encyclopedia.
This article is about graphing calculators as physical tools. "Graphing Calculator" (with a capital G and C) (aka NuCalc) is the name of a computer software tool for Mac OS and Microsoft Windows that performs basic to advanced graphing calculator functions.
A graphing calculator is a special kind of scientific/engineering calculator that is able to draw and/or analyze mathematical function graphs on its display. In addition, graphing calculators can show several lines of text and numbers at a time. Some graphing calculators have color displays.
Hewlett Packard introduced graphing calculators in 1987, in the form of the HP-28C. This was followed by the HP-28S (1988), HP-48SX (1990), HP-48S (1991), HP-48G/GX (1994), HP-38G (1995), HP-39G (199x), HP-40G (199x), HP-49G (1999), and the HP-49G+ and HP-48GII (2003).
Texas Instruments has produced models of graphing calculators since 1990, the oldest of which was the TI-81. Some of the newer calculators are just like it, only with larger memories, which are the TI-82, TI-83 series, (including the TI-83, TI-83 Plus, and TI-83 Plus Silver Edition), and the TI-84 Plus series (including the TI-84 Plus and TI-84 Plus Silver Edition). Other models, designed to be appropriate for students 10–14 years of age, are the TI-80 and TI-73 series (including the TI-73 and TI-73 Explorer). Others are forms that have been modified to be appropriate for calculus, which are the TI-85, TI-86, and TI-89 series (including the TI-89 and TI 89 Titanium). (the latter two also featuring a CAS, like the HP-49 models). Still others are forms with a computer keyboard, the TI-92 series, including the TI-92, TI-92 Plus, and Voyage 200.
There are also graphing calculators available from Casio and Sharp Corporation. Casio has focused its efforts at the high school/junior college user segment, offering relatively easy-to-use graphing features (in color) without very complex and flexible mathematical functions and programming.
