An analytical approximation to the solution of a wave equation by a variational iteration method

In this work, a variational iteration method, which is a well-known method for solving functional equations, has been employed to solve the general form of a wave equation which governs numerous scientific and engineering experimentations. Some special cases of wave equations are solved as examples to illustrate the capability and reliability of the method. The results reveal that the method is very effective. The restrictions of the method are mentioned.
