“…Due to this fact, finding an approximate solution of fractional differential equations is clearly an important task. In recent years, many effective methods have been proposed for the approximate solution fractional differential equations, such as Adomian decomposition method [3,4], homotopy perturbation method [5][6][7][8], homotopy analysis method [9,10], variational iteration method [11], generalized differential transform method [12] and other methods [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. The organization of the paper is as follows: In Section 2, Basic definitions, such as conformable fractional derivative, and conformable fractional integral, will be presented.…”
