Function Grapher is an easy-to-use software to create 2D, 2.5D, 3D function graphs, animations and table graphs.2D Features: explicit, implicit, parametric, and inequality; Cartesian and polar coordinate systems; curve and animation; graph of inverse function and derivative function; parity; maximum, minimum, and inflexion; integral; root; the length of curve; tangent and normal; curvature circle; intersection; line plot; scatter plot; stem plot; step plot; curve smoothing; graph of limit, series and ordinary differential equation.

3D Features: cartesian, cylindrical, and spherical coordinate systems; 3D curve and surface; animation; graph of partial derivative functions; tangent line and normal plane of 3D curve; tangent plane and normal line of 3D surface; graph of 3D vector and vector operation; 3D surface based on table data; surface by rotation; material and light.Ability to create color map, contour plot and vector plot.Ability to move, zoom in, zoom out and rotate graphs.

Ability to save graphs as pgp file or bmp file.Ability to save animation as AVI file.
