Topic 12.2: Backward Divided-Difference Formulae (Theory)

WebApr 11, 2012 · Differences for points near the edges are calculated with lower order. For example, if n=5 and length (f)=10, then 3-point central differencing is used to calculate values at points 2 and 9, 2-point forward differencing is used for point 1, 2-point backward differencing is used for point 10, and 5-point central differencing is used for points 3-7. WebMar 24, 2024 · Newton's forward difference formula is a finite difference identity giving an interpolated value between tabulated points in terms of the first value and the powers of the forward difference . For , the formula states. with the falling factorial, the formula looks suspiciously like a finite analog of a Taylor series expansion. 60燕王套 https://labottegadeldiavolo.com
