One method of proving the existence of solutions for ODEs , where f is continuous, is to approximate f by a sequence of Lipschitz functions for which standard existence results can be applied. This short paper shows conversely that, in a phase space that is not two-dimensional, for each solution of (such solutions may not be unique) there is a sequence of Lipschitz functions which approximate f and which have solutions which converge to the chosen limit.
