WebGregory 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}. WebApr 10, 2024 · The Formula of Linear Interpolation Its simplest formula is provided below: y = y 1 + ( x − x 1) ( y 2 − y 1) x 2 − x 1 It is using the coordinates of two given points to find the best fit curve as a straight line. Then it will give us any required value of y at a known value of x. In this formula, we have the following terms:
