In this thesis, we applied the Homotopy Analysis Method (HAM), which is an analytic technique to obtain symbolic approximate solution for linear and nonlinear dynamical systems. The (HAM) is a strong and easy-to-use for nonlinear Problems, it also has many benefits that makes it different from most analytical methods, such as, it provides us with an easy and simple way to control the convergent region of the series solution. The method is illustrated by two examples of Nonlinear systems. A comparison between the solution obtained by the (HAM) and the exact solution is presented.
