Graphing Calculator is a Mac OS X application that provides graph equations in two, three, and four dimensions.
Graphing Calculator also provides graph explicit functions, implicit relations, parametric curves and surfaces, inequalities, points, vectors, contour plots, density plots, color maps, vector fields, ordinary differential equations, surfaces of revolution, polytopes, coordinate transformations, conformal maps and complex-valued curves, surfaces, and ODEs.
In addition, you will be able to use rectangular, polar, cylindrical, or spherical coordinates. Solve equations numerically, graphically, or symbolically. Create mathematical movies and web pages.
NOTE: To buy Graphing Calculator via the App Store, an Apple account is required.
