6. GDC requirement in DP • Mathematical studies SL- Compulsory to use in all the papers (Students must have access to a GDC at all times) • Mathematics SL- Compulsory to use in paper 2 (Students must have access to a GDC at all times) • Mathematics HL- Compulsory to use in paper 2 (Students must have access to a GDC at all times)

7. How is it used? • 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 alsoprogrammable, allowing the user to create customized programs, typically for scientific/engineering and education applications. Because they have large displays, graphing calculators can also typically display several lines of text and calculations at the same time. • Source: wikipedia
