Error-functions in double-sided Taylor’s approximations. (English) Zbl 1474.26056
Summary: In this paper we introduce the error-functions for one-sided and double-sided Taylor’s approximations of real analytic functions. We illustrate the application of error-functions in the process of generalization of one trigonometric inequality.
