The differential transformation method is a powerful tool which enables to find analytical solution in case
of linear and non-linear systems of differential equations. The method has been successfully applied to linear
and non-linear stiff systems of differential equations. This method is better than numerical methods, since it is
free from rounding off error, and does not require large computer power. In the present paper, the method yields a series solution which converges faster than the series obtained by another methods (see Refs.
[14,12,15]). The numerical results obtained by present method are compared with the analytical solutions.
It is shown that the results are found to be in good agreement with each other
