摘要
This work presents the application of series method to find solutions of differential-algebraic equations systems (DAEs). We present two case studies to show that series method generates approximate solutions for DAEs. The type of tested equations are a linear and a nonlinear DAEs of index-3. What is more, we present the post-processing of the series solutions with Laplace-Pade (LP) resummation method as a useful strategy to find exact solutions or to extend the domain of convergence of the power series solutions.
