Сформулирована задача исследования многочленов 𝐷𝑛(𝑥) на отрезке [0, 1], в рамках которой получены точные выражения и оценки значений на границах и в специальных узлах.</p></abstract><trans-abstract xml:lang="en"><p>The article defines a class of 𝐷𝑛(𝑥) polynomials by specially designed nodes. Each of 𝐷𝑛(𝑥) is the factor of the Chebyshev polynomial of the first kind 𝑇2𝑛(𝑥). The research task forpolynomials 𝐷𝑛(𝑥) on the interval [0,1] is reduced to find values 𝐷𝑛(𝑥). The article contains exact expressions and estimates of values 𝐷𝑛(𝑥) in special nodes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многочлены Чебышева</kwd><kwd>функция Лобачевского</kwd><kwd>оценки.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chebyshev polynomials</kwd><kwd>Lobachevsky function</kwd><kwd>estimations.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Прасолов В.
