Line 5:

Rather informally, to say that a function ''f'' has a limit ''y'' when ''x'' tends to a value ''x₀'' (or to the infinity), is to say that the values taken by the expression ''f(x)'' get close to ''y'' when ''x'' gets close to ''x₀'' (or gets infinitely big). Formal definitions, first devised around the end of the [[19th century]], are given below.

See [[net (topology)]] for a generalisationgeneralization of the concept of limit.
