AbstractKeywords: Wave equation , D'Alembert's formula , Variational iteration method , Homotopy perturbation method. Abstract: In this paper, the variational iteration and the homotopyperturbation methods are adopted to obtain the solution of theone-dimensional wave equation. The solutions procedure reveal thatthe applied methods are very efficient. In addition, the resultobtained is the same as the D'Alembert's formula for the waveequation.
