We discuss a number of different methods for second order differential systems \(\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{x} '' = \underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{F} \left( {t, \underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{x} } \right)\) each of which reduce to two-step methods for linear homogeneous systems \(\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{x} '' + K\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{x} = \underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{g} \left( t \right)\). It is shown that some apparently unconnected methods are closely related when applied to this simple problem.
