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 ) / …

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)

Newton's Interpolation Formulae As stated earlier, interpolation is the process of approximating a given function, whose values are known at tabular points, by a suitable polynomial, of degree which takes the values at for Note that if the given data has errors, it will also be reflected in the polynomial so obtained.. In the following, we shall use forward and backward differences to …
