It is often convenient to apply a list of rules, You apply the rule to an expression using Nfound (* returns number of occurrences *)Ī substitution rule is something like x->2.5 which means Here is a video showing how to develop a Mathematica program using a Notebook in parallel with a text editor.

The solutions to an ODE satisfy existence and uniqueness properties. (PDEs) as a result of their importance in fields as diverse as physics, engineering, A vast amount of researchĪnd huge numbers of publications have been devoted to the numerical solution of differential Runge-Kutta method, but many others have beenĭeveloped, including the collocation methodĪnd Galerkin method. Methods (Milne 1970, Jeffreys and Jeffreys 1988). While there are many general techniques for analytically solving classes of ODEs, the only practical solution technique for complicated equations is to use numerical Morse and Feshbach (1953, pp. 667-674) give canonical Integral transforms suchĪs the Laplace transform can also be used to ( Sturm-Liouville theory) ordinary differentialĮquations, and arbitrary ODEs with linear constant coefficientsĬan be solved when they are of certain factorable forms. Simple theories exist for first-order ( integrating factor) and second-order In general, an th-order ODE has linearly independent solutions.
