iterative formula造句怎么写

The first iterative formula(I) is a one-step iterative formula. It has second order convergence rate at single root, and needn't evaluate derivative of function.

This paper presents a formula of the initial value, a formula of the number of iterative steps and a iterative formula to generate a parametric surfaces by point-by-point method, and a fast point-by-point algorithm for generating rational parametric surfaces algorithm is presented in this paper.

This paper proposes a iterative formula for solution to real roots of nonlinear equations, proves convergence of the iterative series.

The second iterative formula(II) is also one-step iterative formula and has three order convergence at single root.

This paper presents a new iterative formula by which the solution of nonlinear equation had rapid and absolute convergence.
