摘要

Ordinary differential equations are suitable for the mathematical description of time-varying processes such as the behaviour of population numbers, oscillation processes or the effect of acceleration forces. By introducing auxiliary variables, differential equations can be reduced to first-order systems. In some special cases, solutions can be explicitly given by closed formulas.
