GraphNow Function Grapher ver.3.1.7

This graphing calculator offers a professional solution for anyone who graphs functions. It helps to create 2D, 2.5D function graphs(Cartesian and polar), 3D curves, surfaces (Cartesian, cylindrical and spherical), animations and table graphs. High quality graphs can be created by setting the properties of curve, surface, axes and light.
