An improved one-step amplitude-frequency relation for nonlinear oscillators

This paper proposes an amplitude-frequency relation which improves He's simple, one-step, approach for approximating the frequency in the case of the cubic-quintic Duffing oscillator; the relation we apply is a weighted average amplitude-frequency relation.
