The variational iteration method: A highly promising method for solving the system of integro-differential equations

This paper applies He's variational iteration method for solving two systems of Volterra integro-differential equations. The solution process is illustrated and various physically relevant results are obtained. Comparison of the obtained results with exact solutions shows that the used method is an effective and highly promising method for various classes of both linear and nonlinear integro-differential equations.
