Approximation of Functions by Polynomials in C[-L, 1]
Approximation of Functions by Polynomials in C[-L, 1]
Abstract A pointwise estimate for the rate of approximation by polynomials , For 0 ≤ ƛ ≤ 1, integer r, and δ n (x) = n -1 + φ(x), is achieved here. This formula bridges the gap between the classical estimate mentioned in most texts on approximation and obtained by …
