'''Numerical methods for ordinary differential equations''' are methods used to find numerical approximations to the solutions of [[Ordinary differential equation|ordinary differential equations]] (ODEs).

Their use is also known as "numerical integration", although this term is sometimes taken to mean the computation of integrals.

== Description ==

Many differential equations cannot be solved using symbolic computation ("analysis"). For practical purposes, however – such as in [[engineering]] – a numeric approximation to the solution is often sufficient. The algorithms studied here can be used to compute such an approximation.

An alternative method is to use techniques from [[calculus]] to obtain a [[series expansion]] of the solution.

Ordinary differential equations occur in many scientific disciplines, for instance in [[physics]], chemistry, biology, and economics.

In addition, some methods in numerical [[Partial differential equation|partial differential equations]] convert the partial differential equation into an ordinary differential equation, which must then be solved.
