Abstract

One of the most important sciences that is actively used in scientific and technical activities is mathematics, which plays the role of language. The profession of an engineer puts forward serious requirements for the mastery of many professional knowledge based on mathematical theory, in particular the theory of series, which is widely used in various theoretical studies related to the calculation of function values, integrals, and the approximate solution of differential equations. This paper examines the study of the convergence of numerical series constructed using the elements of the tangram square.
