Hashim %J International Journal of Differential Equations %D 2009 %I Hindawi Publishing Corporation %R 10.1155/2009/842094 %X Direct solution of a class of nth-order initial value problems (IVPs) is considered based on the homotopy analysis method (HAM). The HAM solutions contain an auxiliary parameter which provides a convenient way of controlling the convergence region of the series solutions. The HAM gives approximate analytical solutions which are of comparable accuracy to the seven- and eight-order Runge-Kutta method (RK78). %U http://www.hindawi.com/journals/ijde/2009/842094/
