Variable mesh finite difference method of fifth order have been derived for solution of singular two point boundary value problem, which reduces to the method of order six, for uniform mesh case. These methods are self starting and are exact for u =r-1 • The convergence of the sixth order method is discussed. The absolute error, for solution of four problems, two linear and two nonlinear are listed to show the accurate and effectiveness of the present method.
