infinite series
English[edit]
Noun[edit]
infinite series (plural infinite series)
 (analysis) Any expression that represents the addition a countably infinite number of ordered summands, often explicitly indexed by the positive or nonnegative integers.

In 1734, Leonhard Euler solved the Basel problem by summing the infinite series .

Usage notes[edit]
The sum of an infinite series is formally defined as the limit, if it exists, of the sequence of partial sums of the first n elements as n increases to infinity (i.e., becomes arbitrarily large). If the limit exists, the series is said to be convergent; otherwise it is divergent.
