Lagrange interpolation questions and answers. 9 s . Solution (b). It highlights the method's simplicity, the potential for computational errors, and the importance of understanding the underlying function's smoothness. Several example problems are provided to illustrate the application of Lagrange's Polynomial Interpolation The following questions are based upon the material in sections 1. Lagrange’s interpolation formula can be used whether the values of x, the independent variable are equally spaced or not whether the difference of y become smaller or not. 1 to 1. Oct. three points closest to t 14 . 8189 and log10 661 = 2. Solution: By Lagrange's interpolation formula, we have 11. 9, they do n t bracket it. . Figure 1: Two Lagrange polynomials de ned by the given sequence of interpolating points. Using graphic method, find the value of y when x = 48 from the following data: 2. U N/D 2014] Solution: Let y = f (x) be a function which takes the values y0, y1, yn corresponding to x = x0,x1. In this article, we will learn about, Lagrange Interpolation, Lagrange Interpolation Formula, Proof for Lagrange Interpolation Formula, Examples based on Lagrange Interpolation Formula, and others in detail. U CBT N/D 2010] [M. The following data relates to indirect labour expenses and the level of output We determine the Lagrange coe¢ cient polynomials, and the Lagrange interpolating poly-nomial, in terms of t; and then substitute t = 6x to obtain the Lagrange interpolating polynomial in terms of x: Hence, using Solution The correct answer is (A). Use Lagrange's method to find log10 656, given that log10 654 = 2. State Lagrange's interpolation formula. What is the Lagrange's formula to find y, if three sets of This set of Engineering Mathematics Multiple Choice Questions & Answers (MCQs) focuses on “Lagrange Method of Multiplier to Find Maxima or Minima”. U N/D 2012] 13. 1. 9 s that also bracket t 14 . 8182, log10 659 = 2. This would be performing extrapolation, not interpolation. 2 1. 3 of the notes. [A. 8202 Solution: Given: [A. 1. x Then, Lagrange's interpolation formula is 2. Example Solved Problems with Answer, Solution, Formula - Lagrange’s interpolation formula | 12th Business Maths and Statistics : Chapter 5 : Numerical Methods SHORT QUESTIONS AND ANSWERS 1. , 2000, A. Book back answers and solution for Exercise questions - Maths: Numerical Methods: Interpolation: Problem Questions with Answer, Solution Exercise 5. U. April 2000, Tvli M/J 2010, CBT A/M 2011] [A. Find the Lagrangian interpolating polynomial for the following data: 12. The answer to this question depends upon how the speci c volume of v = 0:042 m3/kg compares with the speci c volume of saturated Freon-12 vapor, vg, at a pressure of 400kPa. Because f is thrice di erentiable over R, the Lagrange Interpolation Remainder Theorem states that for every x 2 [0; 2] there exists some zx 2 (0; 2) The document discusses Lagrange's interpolation method, which is a straightforward approach for finding a polynomial that interpolates unevenly spaced data. Although t e data points in choice (B) are closest to 14. Choices (C) and (D) b Jul 23, 2025 ยท The interpolation method is used to find the new data points within the range of a discrete set of known data points. U N/D 2011] [A. In a simple one-constraint Lagrange multiplier setup, the constraint has to be always one dimension lesser than the objective function. 8156, log10 658 = 2. a) True b) False View Answer Lagrange’s formula for inverse interpolation is used when we are required to find the value of x corresponding to a certain value of y from a given set of values of x and y. c8tw tup3k rd x2vsf wxk 9bnw pr 1vtp w2vlngc9 3f
