A numerical solution of classical Van der Pol-Duffing oscillator by He's parameter-expansion method

In this paper, the classical Van der Pol-Duffing Oscillator is studied. We provide an approximate solution for this equation using parameter expansion method. Also, we obtain approximate values for frequency of the equation. The parameter-expansion method is more efficient than the perturbation method for this equation because the method is independent of perturbation parameter assumption.
