    16/12/2018 · 1. What is Interpolation For Central Difference in Numerical Analysis ? 2. Stirling, Gauss Forward, Gauss Backward & Bessel's Interpolation Formula of Equal Interval For Central Difference in applying Newton’s backward interpolation formula given by: , , , Also from table , , , , Substituting these values in , we get 7.2.3 Gauss’s Forward and Backward Difference Formulae Gauss central difference formula is used to interpolate the values of near the middle of the table. Newton’s forward difference formula is given by: Now
