Числовые ряды. Основные понятия - bezbotvy

A numerical series is an ordinary infinite set of numbers related by some rule. Each series can be described by a common term, can converge or diverge, and can be a constant-sign or alternating-sign numerical series. To determine whether a series converges, special convergence tests are used, which I will discuss in other videos and provide links to on specclass.ru, as well as in this description.
