Four types of 3D graphs (Sphere,Cylinder,Plane and Line) are available. It is easy to draw 3D graphs using templates. Recognize combinations of graphs and interactive relationships between two or three graphs mathematically. E-CON4 Application: This feature, with a simple user interface, is effective for collecting data for use in classroom science and technology lessons.This feature has Auto-ID recognition, which enables drawing of graphs of collected data automatically with no complicated settings. Examination Mode: This mode allows you to quickly prepare your calculator for exams. This mode restricts access to memory, programs, functions and applications, so that these features would not be available during exams. • Graphic Calculator with 2900+ functions. • All advanced Algebraic, Trigonometrical, Calculus, Statistics functions • Advanced 3D Graphing • Multiple types of Graphic features • List based Statistics, Regression and Graph plot • Built in apps for research and modelling • App can be transferred to calculator through supplied USB cable. • Comes with slide-on hard case • Recommended for IB, SAT, ACT, PSAT Students
