Abstract

The forced and undamped harmonic oscillator revisits with new and fundamental aspects The study discloses complementary and -so far overlooked- intrinsic properties Despite its simplicity the model is shown to be characterized by countless -theoretically unlimited- sequences of intricate solutions Such hierarchies including the familiar period-doubling series -or equivalently subharmonic cascades- usually typify complex nonlinear dynamical systems The remarkable similarity between the numerically simulated and the analytically predicted solutions confers the model unquestionable credit It takes simple trigonometry -at the reach of the willing undergraduate student- to fully grab the essence of the new outcomes
