“…Bagley-Torvik-type fractional differential equations have been studied both numerically and analytically in numerous articles. Among the methods used to solve this equation, we mention the following: numerical methods [5], Adomian decomposition method [6], discrete spline methods [7], Haar wavelet method [8,9], homotopy perturbation method [10], sinc collocation method [11,12], cubic spline method [13], quadratic spline solution [14], B-spline collocation method [15,16], Chebyshev collocation method [17], hybrid functions approximation [18], harmonic wavelets [19], predictor-corrector method of Adams type [20], spectral methods [21], fractional natural decomposition method [22], and finite element method [23]. e motivation of this paper is to introduce a new method for obtaining analytical approximate solutions for fractional differential equations.…”
