In order to achieve higher computational precision in approximating the first-order derivative of the target point, Lagrange numerical-differentiation formulas (also known as one-step-ahead numerical-differentiation formulas) are presented. These formulas greatly remedy some intrinsic weaknesses of backward numerical-differentiation formulas and overcome limitation of central numerical-differentiation formulas. In addition, a group of formulas are proposed to obtain the optimal sampling gaps. Moreover, the error analyses of Lagrange numerical-differentiation formulas and backward numerical-differentiation formulas are further investigated. Numerical ...
