A Note on Lagrange Interpolation of |<i>x</i>| on the Chebyshev and Chebyshev–Lobatto Nodal Systems: The Even Cases

Throughout this study, we continue the analysis of a recently found out Gibbs–Wilbraham phenomenon, being related to the behavior of the Lagrange interpolation polynomials of the continuous absolute value function. Our study establishes the error of the Lagrange polynomial interpolants of the functi...
