Small oscillations evolved a great deal from Klein to Robinson. We propose aconcept of solution of differential equation based on Euler's method withinfinitesimal mesh, with well-posedness based on a relation of adequalityfollowing Fermat and Leibniz. The result is that the period of infinitesimaloscillations is independent of their amplitude.  Keywords: harmonic motion; infinitesimal; pendulum; small oscillations
