Third order newton interpolating polynomial
WebFrom this divided difference table, only the underlined values will be used in the Newton’s divided difference interpolation formula. Now, we obtain the Newton’s divided difference interpolating polynomial as \begin{array}{r}{f(x)\cong2.8156+0.00065\times(x-654)+(x-654)(x-658)\times(0.00001)}\end{array}

Given a set of 3 data points $\{(0,1), (2,5),(4,17)\}$, we shall determine Newton’s interpolation polynomial of degree 2 …
WebConclusion: Linear interpolation is suitable only over small intervals. 4.2 Polynomial Interpolation Since linear interpolation is not adequate unless the given points are closely spaced, we consider higher order interpolating polynomials. Let f(x) be given at the selected sample of (n + 1) points: x 0 < x 1 < ··· < x n, i.e., we have (n+1 ... WebExpert Answer 1st step All steps Final answer Step 1/3 To use Newton's interpolating polynomials, we first need to order the data points by increasing values of t: Explanation: We will use these points to construct a table of divided differences: f [ t i] z 0 = 6 z 1 = 7.752 z 2 = 10.256 z 3 = 36.576 z 4 = 66 z 5 = 125.168 Explanation:
