Analogs of recurrent Newton formulas
Russian Mathematics, 2009For a system of algebraic equations, the recurrent Newton formulas for evaluating power sums of roots in terms of coefficients are well-known. In this paper, analogs of these formulas are obtained for nonlinear nonalgebraic equations. The main idea is to study sums of negative powers of roots.

An Extension of the Leibniz-Newton Formula
2004In this section we are going to present a slight extension of the Leibniz-Newton formula for the computation of the definite integral, an extension that can be applied also in the case of some integrable functions which do not admit ...

Newton's Formula and the Continued Fraction Expansion of √d
Experimental Mathematics, 2001It is known that if the period s(d) of the continued fraction expansion of √d satisfies s(d) ≤ 2, then all Newton's approximants are convergents of √d, and moreover Rn = P2n+1/q2n+1 for all n ≥ 0. Motivated by this fact we define j = j(d, n) by Rn = P2n+1+2j/ q2n+1+2j if Rn is a convergent of √d, and define b = b(d) by b = |{n : 0 ≤ n ≤ s-1 and Rn is a

Generalized Newton–Leibniz Formula
2016One of the (if not the) most important theorems of classical analysis is the Newton–Leibniz formula: $$\displaystyle{ \int _{a}^{b}f\ dx = F(b) - F(a), }$$ allowing us to compute many integrals. The purpose of this chapter is to extend its validity to Lebesgue integrable functions.

Thermodynamically consistent quasi‐Newton formulae
AIChE Journal, 1985AbstractNewton and quasi‐Newton methods have been used in chemical process design and optimization calculations for quite some time. They continue to be used today, both in the traditional sense and as part of the more recent hybrid method. While Newton‐based fixed‐point methods have been used to solve many different kinds of chemical process design ...

On the Error Analysis Associated with the Newton-Cotes Formulae
International Journal of Computer Mathematics, 2002In the current paper, the truncation error (TE) for both the closed and open Newton-Cotes quadrature formulae for numerical integration is investigated and calculated for n = 1, 2, @, 12 in both cases.

Newton's Interpolation Formulas. An unpublished Manuscript of Sir Isaac Newton
Journal of the Institute of Actuaries, 1927The mortality of Europeans in West Africa has on several occasions been the subject of discussion in this Institute or of note in the pages of the Journal. In 1886 Dr. T. B. Sprague read a paper on the mortality of Europeans in the Congo, based on the statistics from Stanley's work on the Pounding of the Free State: In 1892 Dr. T. G. Lyon contributed a
