Visual Calculus is an easy-to-use calculus grapher for
Graphing limit, derivative function, integral, 3D
vector, series, ode etc. Which can create 2D, 2.5D and
3D function graphs, animations and table graphs. 2D
Features: explicit, implicit, parametric, and in
equation; Cartesian and polar coordinate systems;
curve and animation; graph of inverse function and
derivative function; parity; maximum, minimum, and
inflexion; integration; root; the length of curve;
tangent and normal; curvature circle; intersection;
line plot; scatter plot; stem plot; step plot; curve
smoothing. 3D Features: cartesian, cylindrical, and
spherical coordinate systems; 3D curve and surface;
animation; 3D surface based on table data; surface by
rotation; 3D vector; tangent and normal of 3D curve
and surface; 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 text file or bmp file. Ability to save
animation as AVI file.
