In mathematics, divided differences is an algorithm, historically used for computing tables of logarithms and trigonometric functions. [citation needed] Charles Babbage's difference engine, an early mechanical calculator, was designed to use this algorithm in its operation. [1] Divided differences is a recursive division process.
This expression is Newton's difference quotient (also known as a first-order divided difference). The slope of this secant line differs from the slope of the tangent line by an amount that is approximately proportional to h. As h approaches zero, the slope of the secant line approaches the slope of the tangent line.
Given n + 1 points, there is a unique polynomial of degree ≤ n which goes through the given points. Neville's algorithm evaluates this polynomial. Neville's algorithm evaluates this polynomial. Neville's algorithm is based on the Newton form of the interpolating polynomial and the recursion relation for the divided differences .
The divided difference methods have the advantage that more data points can be added, for improved accuracy. The terms based on the previous data points can continue to be used. With the ordinary Lagrange formula, to do the problem with more data points would require re-doing the whole problem.

The Denver Broncos faced $1.9 million in fines in 2001 and 2004 for circumventing the NFL’s salary cap during the mid-1990s. The violations were tied to deferred payments in contracts with ...
Nvidia stock rose nearly 5% on Tuesday, following bullish notes from Wall Street analysts citing strong chip demand ahead of its earnings report set for Wednesday afternoon.
The angle difference identities for and can be derived from the angle sum versions by substituting for and using the facts that = and = (). They can also be derived by using a slightly modified version of the figure for the angle sum identities, both of which are shown here.
