Comparison differential transformation technique with Adomian decomposition method for linear and nonlinear initial value problems

In this paper, we will compare the differential transformation method DTM and Adomian decomposition method ADM to solve partial differential equations (PDEs). The definition and operations of differential transform method was introduced by Zhou {[}Zhou JK. Differential transformation and its application for electrical circuits.

Higher-order dimensional differential transformation are applied to a few some initial value problems to show that the solutions obtained by the proposed method DTM coincide with the approximate solution ADM and the analytic solutions.
