Useful in learning and teaching
geometry, trigonometry, function, equation, vector, 3D geometry,
3D plotting and preliminary infinitesimal calculus. Mathsay 4.5 (update in Aug. 7, 2008) is new powerful math software for students and teachers in middle school, in high school and in University. It shows the concepts of mathematics and makes analysis and calculation in the graph. It offers a tool to explore, visualize, and solve even the most complex mathematical problems, and make math expression and symbol easily. Not only can it help students grasp the concepts and do math exercise, but also can it make teachers to dynamically plot and demonstrate in the class with the interactive function.
