Equa-tions that are neither elliptic nor parabolic do arise in geometry (a good example is the equation used by Nash to prove isometric embedding results); however many of the applications involve only elliptic or parabolic equations. Their use is also known as "numerical integration", although this term can also refer to the computation of integrals.Many differential equations cannot be solved using symbolic computation ("analysis").
