Mathematical Knowledge in Mathematica
Mathematica incorporates the knowledge from the world's mathematical handbooks — and uses its own revolutionary algorithms to go much further.
Mathematica knows about all the hundreds of special functions in pure and applied mathematics.
Mathematica is now able to do vastly more integrals than were ever before possible for either humans or computers.
