Visual Calculus is a user-friendly software for creating various calculus graphs, including limit, derivative function, integral, 3D vector, series, and ode. It supports 2D, 2.5D, and 3D function graphs, table graphs, and animations.

Visual Calculus offers several 2D features, including explicit, implicit, parametric, and equations, graphing in both Cartesian and polar coordinate systems. It also has capabilities to graph inverse and derivative functions, parity, maximum, minimum, and inflection, integration, root, length of curve, tangent and normal curvature circle, intersection, line plot, scatter plot, stem plot, step plot, and curve smoothing.
In addition to the 2D functions, Visual Calculus also provides 3D features, such as Cartesian, cylindrical, and spherical coordinate systems, 3D curve and surface graphs, animations, and 3D surface based on table data, surface by rotation, 3D vector, tangent, and normal of 3D curve and surface, material and light, as well as the ability to create color map, contour plot, and vector plot.
The software also allows users to move, zoom in, zoom out and rotate graphs with ease. Saving graphs as text or bmp files is also possible, making sharing and editing a breeze. Visual Calculus also offers the ability to save animations as AVI files, allowing users to store and share their dynamic graphs.
Overall, Visual Calculus, with its easy-to-use interface, offers the user a wide variety of functions and features to create comprehensive visualizations and simplified presentations of complex calculus concepts.
