Modifying Adomian Decomposition Method for Linear Ordinary Differential Equations

Applying Adomian decomposition method to damped forced oscillator, gives a polynomial asthe approximate solution of the problem if the excitation term replaced with its Taylor series aroundthe initial value point. In this paper, we use the interpolation of this term at the required interval inspite of its Taylor series. The numerical results show that the method at identical conditions givesmore suitable solutions
