Let Лnbe the set of all polynomials of degree at most n with complex coefficients. As usual denote byand U m (x) : = (1= x 2 ) −1/2 sin((m+1)arc cos x) the Tschebyscheff polynomials of degree m of the first and second kind, respectively. Furthermore, let us write ∥·∥ for the maximum norm on the unit interval, i. e. $$\left\| P \right\|: = \begin{array}{*{20}c} {\max } \\ { - 1 \leqq x \leqq 1} \\ \end{array} |p(x)|$$.
