Part of the Applied Mathematical Sciences book series (AMS, volume 76)


Exact solutions of mathematical problems are often difficult or impossible to obtain and one therefore often tries to find approximate solutions. There are many methods for doing this, and we shall briefly describe some of the methods. For a given problem, a mixture of various methods may be used.
