In this paper, we consider the homtopy analysis method (HAM) for solving
nonlinear ordinary differential equation with boundary conditions. The partial sum
of solution series is determined using finite difference method and spectral
method. These methods are used for solving deformation equation. For improving
the rate of convergence, we apply the methods of Marinca and Niu-Wang. The
results are compared with finite difference method and spectral method. Unlike
HAM, these methods don’t need convergence control parameter. Numerical
experiments show efficiency and performance of proposed methods.
