It researches approximative opportunities of concrete approximating structures. In the article one of the actively studied in recent times types of approximating operators — Baskakov's trigonometric operators. Some characteristics of these operators are being investigated: norms and approximation constants, assessment and improved. In particular, the assessment of their difference is obtained.тригонометрические операторы Баскакова, аппроксимационные оценкиBaskakov’s trigonometric operators, approximate estimates. Paper received
