Smallest Element is Infimum/Examples/Example 2

Example of Use of Smallest Element is Infimum

Let $T$ be the subset of the set of real numbers $\R$ defined as:

$T := \set {x \in \R: 1 \le x < 2}$

$T$ has a smallest element $1$.

Hence from Smallest Element is Infimum it follows that $1$ is also the infimum of $T$.
