Abstract: In this paper we consider applications of extrapolation method to the numerical solution of singular perturbation problem for etliptic-parabolic equation in order to manifesting accuracy of approximations and estimate the order of accuracy.Concerning the uniform convergence in ref.[1].its proof is given in the appendix.
