It also generates a self-checking answer key. MuPAD MuPAD is a general purpose computer algebra system for symbolic and numerical computations. NetMath NetMath is a web browser which knows something about math. It has built-in plotting engines and the ability to communicate with computation servers. This makes it possible to do local graphics, zooming and panning, while taking advantage of sophisticated computational programs.
Documents contain active and editable items, and the results of computations appear in the document.
Nightfall is an interactive application to simulate eclipsing binary stars, and to produce animated views, synthetic lightcurves and more.
