โฆ Synopsis
The author proposes some stable and convergent two-point integration formulae which are particularly well suited to systems of ordinary differential equations with oscillating solutions. The numerical integration algorithms are based on the representation of the theoretical solution by the perturbation of a polynomial interpolating function with a trigonometric function. For non-oscillatory systems, the proposed schemes reduce to the normal Taylor series.

A measure of the stability properties of numerical integration methods for ordinary differential equations is provided by their stability region, which is that region in the complex (AtX) plane for which a given method is stable when applied to the differential equation with a time-step At. Free pa
A numerical integration scheme which is particularly well suited to initial value problems having oscillatory or exponential solutions is proposed. The derivation of the algorithm is based on a representation of problems (that is problems having oscillatory or exponential solutions), the complex par
The existing literature usually assumes that second order ordinary differential equations can be put in first order form, and this assumption is the starting point of most treatments of ordinary differential equations. This paper examines numerical schemes for solving second order implicit non-linea
