Graphing Calculator Viewer is only a demonstration program of the Graphing Calculator full version. You cannot utilize the software to graph functions, but you can open examples, demos, and help. You can only perform zoom, change slider values, show axes, copy to clipboard, and play the examples. Examples are for basic functions; two dimension cycloids, spirals, torus cuts, etc.; three dimensions with implicit 3D surface, parametric 3D curve, conical helix, four dimensions hypercube, sphere, etc. You can also check examples of complex variables and coordinate transformations: equations for circles with complex functions, numbers, density, orbit, and more; demo equations like dancing, heart, horn, Klein, landscape, rose, staircase, etc. Demos are for basic functions, curves, surfaces, fields, four dimensions, complex variables, exponential functions, and full demo of the program. Help is provided for the entire Graphing Calculator program including types of graphs, graphs involving complex numbers, recognized functions, Greek letters and special symbols, graphing variables, math and graph pane shortcuts, etc. Also includes links for help with algebra, calculus, trigonometry, geometry, statistics, complex numbers, and four dimensions.
