| Abstract: | This paper uses the homotopy analysis for the Duffing-harmonic oscillator. The auxiliary parameter in the deformation equation is numerically determined. The response and the frequency of the Duffing-harmonic oscillator are calculated. The analytical results are validated in numerical simulations. |
| Keywords: | Duffing-harmonic oscillator homotopy analysis approximate solution |
