A graphing calculator (also graphics / graphic calculator) typically refers to a class of handheld calculators that are capable of plotting graphs, solving simultaneous equations, and performing numerous other tasks with variables. Most popular graphing calculators are therefore also programmable, allowing the user to create customized programs, typically for scientific/engineering and education applications. Due to their large displays intended for graphing, they can also accommodate several lines of text and calculations at a time. Some graphing calculators also have colour displays, and others even include 3D graphing. More recent full colour graphing calculators like the Casio fx-CG10/20 and the Texas Instruments Nspire CX (both released in 2011) also feature animated and interactive drawing of math plots (2D and 3D), other figures such as animated Geometry theorems, preparation of documents which can include these plots and drawings, etc. This is giving the new graphing calculators a presence even in high school courses where they were formerly disallowed.
