Newton forward difference formula
WitrynaGregory Newton’s is a forward difference formula which is applied to calculate finite difference identity. Regarding the first value f 0 and the power of the forward difference Δ, Gregory Newton’s forward formula gives an interpolated value between the tabulated points. The interpolated value is expressed by {fp}.
