We also explain that our theorem makes more sense with a striking example. We study the quantitative estimates of linear operators. In the final section, we summarize our new results.enginfo:eu-repo/semantics/closedAccessKorovkin type approximation theoryPower series methodRate of convergenceLinear operatorsAn extension of Korovkin theorem via power series methodArticle740008548561000012-s2.0-85138305378
