@Jean-Sébastien I actually had never seen that, in any books I've read.

comment Limits, textbook error?
That method... I'd never accept that, you can build a function that goes as high as you want before making it go to zero or any other number, and that method would give an $\infty$ limit when there is a finite limit.

comment Torsion group is a subgroup.
The notation $|g|$ for an element refers to the size of the subgroup that it generates. $$|g|=|\lbrace 1,g,g^{-1},g^2,g^{-2},...\rbrace |$$ If the group is finite then the size will be the least integer $n$ such that $g^n=1$
