第一条就是这种方法的核心,称为牛顿迭代公式(Newton's Raphson iterative formula)。与其他方法相比,其逼近速度会更快,尤其是在近似的精度较高时尤为明显。 例题(Example) Find the root of the functionobtained after the first iteration on application ofNewton-Raphson schemeusing an initial guess of. Given ...

The error ε2 = x0 –a2 of the new value a2 is related to the old error ε1 = x0 –a1 by the formula where f”(ξ) is the value of the second derivative of the function f(x) at some point ξ that lies between x0 and a 1. It is sometimes recommended that Newton’s method...
An analog of the Newton–Raphson formula, which applies in the case of multiple roots, has been given by Schrder. It is considered that a zero of exact multiplicityis available, then the Newton–Raphson formula is replaced by Schrder's formula. With this modification, the difficulties because...
Newton-Raphson Method Letf(x)f(x)be a differentiable function and leta0a0be a guess for a solution to the equationf(x)=0f(x)=0We can product a sequence of pointsx=a0,a1,a2,…x=a0,a1,a2,…via the recursive formulaan+1=an−f(an)f′(an)an+1=an−f(an)f′(an)that are...
Question: Let f(x)=x2-2x+2(a) Find the Newton-Raphson formula pk=g(pk-1).(b) Start with p0=-1.5 and find p1,p2 and p3. Let f(x)=x2-2x+2 (a) Find the Newton-Raphson formula pk=g(pk-1). (b) ...
The general iterative formula for this method would be: (1.48a)xn+1+=xn−f′(xn)f″(xn)+[f′(xn)]2−2f″(xn)f(xn)f″(xn) or (1.48b)xn+1−=xn−f′(xn)f″(xn)−[f′(xn)]2−2f″(xn)f(xn)f″(xn) The choice between Eq. (1.48a) and Eq. (1.48b) will ...
Calculations are presented for the E3Σu- state of O2. MINR approaches may be useful when small eigenvalues of the Hessian are present. Since the MINR formula involves the product of third-derivative matrices with vectors, explicit evaluation of the third-derivative matrices is avoided. 展开 ...
In this paper we tried to develop Newton Raphson method (abbreviated N-R) to construct new formula which more practice in solving nonlinear problems that are f(x) = 0. Newton homotopy (linear homotopy) H(x, t)=f(x)+(1-t)f(x (0)) had been used in developing Newton Raphson formula...
