Sum to product sin
WebThe infinite sequence of additions implied by a series cannot be effectively carried on (at least in a finite amount of time). However, if the set to which the terms and their finite sums belong has a notion of limit, it is sometimes possible to assign a value to a series, called the sum of the series.This value is the limit as n tends to infinity (if the limit exists) of the …
