The extrapolation method of two-order and three-point numerical differential formulas

Qiang Wang

Abstract

The gradual approximate expansion formulas of two order and three points numerical differential formula error are obtained by Taylor Formula.The convergence order of two order and three points numerical differential formula is improved by Richardson Extrapolation Method.High precision formulas of two order numerical differential are obtained.
