Solution of differential algebraic equations via semi-analytic method

Differential algebraic equations arise in many applications. In this paper, the homotopy perturbation method is applied to solve differential algebraic equations. In this method, the solution is found in the form of a convergent series and usually converges to the exact solution. In addition, the terms of the series can be computed easily. A few examples are presented to illustrate the method. The results show the simplicity and efficiency of the proposed method.
