  • Abstract
    Tables are presented which make possible quick approximation of a curve by a series of Chebyshev polynomials: f(x) ≈ a0/2 Σi = 1naiTi(x); nmax= 10 The given curve is replaced by linear pieces between 21 equidistant points in the interval 〈- 1; + 1〉. The nth coefficient is computed as an= Σ Kn,jkj+ Σ Qn,jqjwhere Kn,j, Qn,jare constants of the tables and ki, qjare constants of the linear piece y = kjx + qjin the jth interval.
