Exact solutions for some of the fractional differential equations by using modification of He’s variational iteration method

In this paper, the modification of He s variational iteration method (MVIM)is developed to solve fractional ordinary differential equations and fractional partialdifferential equations. It is used the free choice of initial approximation topropose the reliable modification of He s variational iteration method. Some of the fractional differential equations are examined to illustrate the effectiveness and convenience of the method. The results show that the proposed method has accelerated convergence.
