摘要：In this work, a modified decomposition method namely Sumudu-Adomian Decomposition Method (SADM) is implemented to find the exact and approximate solutions of fractional order telegraph equations.The derivatives of fractional-order are expressed in terms of caputo operator.Some numerical examples are illustrated to examine the efficiency of the proposed technique.Solutions of fractional order telegraph equations are obtained in the form of a series solution.It is observed that the solutions of fractional order telegraph equations converge towards the solution of an integer-order problem, which confirmed the reliability of the suggested method.
