Abstract
We present an implicit eighth-order finite difference method for the general second order non-linear differential equation Yn=f(t,y,y) subject to the initial conditions y(to) =yo, y(to)=yO. The method is based on mixed interpolation containing a parameter which can be used to improve the accuracy. The same technique gives rise to an explicit sixth-order integration scheme. Numerical solutions of problems are given to illustrate both methods.
