The Definitive Guide to upper and lower limits
If $f$ is an actual-valued perform outlined over a set $Esubset mathbb R$ (or $subset mathbb R^k$), the upper and lower limits of $f$ at $x_0$ are denoted by. Put simply, any quantity beneath the limit inferior is definitely an eventual lower bound for your sequence. Merely a finite variety of aspects of your sequence are less than b − ε display
