Initial-value problems: multi-step methods,neconomic for general use. Their local truncation error is of rather low order, with the result that to achieve good accuracy we need to use either: (a) a rather small step-by-step interval, involving many steps to cover a specified range; or (b) one of our correcting devices which involve some addi

Global (finite-difference) methods for boundary-value problems,derived initial-value problems./In global methods all the boundary conditions play equal parts from the beginning and are involved in all parts of the computation. There are essentially two main types of method. The first, considered in this chapter, is the class of finite-difference methods, in whi

Expansion methods, methods clearly give exact solutions when these are polynomials of appropriate degree. For more general functions, local truncation errors depend on the accuracy with which the solution can be approximated by a polynomial. It is sometimes more convenient to make quite explicit this relation with po

Algorithms,pters for the solution of ordinary differential equations. Most computing services provide a reasonably large range of numerical software, the computer having permanently available in its store a number of routines for solving standard problems in numerical analysis, including the solution of ordina

Expansion methods,lynomials, and we may then be able to calculate the coefficients .. of an approximating expansion . rather than working with a representation of the approximate solution at a set of discrete points. For some simple classes of problems these methods are particularly useful for both initial-value and boundary-value problems.
