A graphing calculator (also graphics / graphic calculator) is a handheld calculator that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are also programmable, allowing the user to create customized programs, typically for scientific/engineering and education applications. Because they have large displays, graphing calculators also typically display several lines of text and calculations at the same time.
Casio produced the first commercially available graphing calculator, the fx-7000G, in 1985. Casio's innovations include an icon menu for easy access to functions (1994, FX-7700GE and later), graphing in several colors (1995, CFX-9800G), expandable memory (FX-9860SD), textbook-like input and output (2009, FX-9750GII & 9860GII), backlit screen (2009, FX-9860 Slim & GII), full-color, high resolution backlit screen (2010, FX-CG10/CG20 PRIZM).
Sharp produced its first graphing calculator, the EL-5200, in 1986. Since then Sharp's innovations include models with a touchscreen (EL9600 series), Equation Editor (textbook-like input) (EL-9450 and later), and reversible keyboard to ease learning (one side has basic functions, the other side has additional functions) (EL-9900).
