infinite population
  پرینش ِ بیکران   
porineš-e bikarân

Fr.: population infinie   

A → statistical population consisting of individuals or items which either possesses the infinite property through some limiting process or is non-enumerable.

infinite series
  سری ِ بیکران   
seri-ye bikarân (#)

Fr.: série infinie   

A series with infinitely many terms, in other words a series that has no last term, such as 1 + 1/4 + 1/9 + 1/16 + · · · + 1/n2 + ... . The idea of infinite series is familiar from decimal expansions, for instance the expansion π = 3.14159265358979... can be written as π = 3 + 1/10 + 4/102 + 1/103 + 5/104 + 9/105 + 2/106 + 6/107 + 5/108 + 3/109 + 5/1010 + 8/1011 + ... , so π is an "infinite sum" of fractions. See also → finite series.

infinite; → series.
