This polynomial is called the Newton - Gregory backward difference formula. The error in this interpolation Example : Find f (0.15) using Newton backward difference table from the data s = ( x - xn ) / h = (0.15 - 0.5) / 0.1 = -3.5 = 0.97943 - 0.315 - 0.01706 + 0.000765625 + 0.00033086 = 0.14847 Error in the approximation = 2.734375 x 10-7 f5( x)

Oct 17, 2017 · Thus, the first backward differences are : NEWTON’S GREGORY BACKWARD INTERPOLATION FORMULA: This formula is useful when the value of f(x) is required near the end of the table. h is called the interval of difference and u = ( x – an ) / h, Here an is last term. Example: Input : Population in 1925. Output : Value in 1925 is 96.8368. Below is the implementation of the Newton backward interpolation method.
