Abstract
In this paper, a novel analytical approximation to the nonlinear Duffing-harmonic oscillator
is presented. The variational iteration method (VIM) is used to obtain some accurate
analytical results for frequency. The accuracy of the results is excellent in the whole range
of oscillation amplitude variations.
