Approximation Chebyshev roots Interpolation Lagrange PolynomialAbstract
This research paper aims to compare different polynomial interpolation methods: traditional Lagrange, first modified Lagrange, second modified Lagrange) Barycentric form (, in addition to Newton’s method and Chebyshev polynomial interpolation. Each of these methods is studied using both equally spaced points and Chebyshev points, focusing on how to improve approximation accuracy through point selection and distribution. Additionally, some advantages and disadvantages of each method are assessed
