comment Degeneracy number of a ring graph
@triomphe yes, i am now confused too. the definition on wiki does not restrict graph size. need to look more into it, i am sorry.

comment Degeneracy number of a ring graph
@triomphe your last formulation is wrong, degeneracy is $$\min\{\max \mathrm{deg}(s) | s \in S\}.$$ This way, tree is 1-degenerate and cycle is 2-degenerate and star is 1-degenerate also. I got confused myself also, sorry.

comment How do I do Linearization at a point that lies on a curve?
@Cozen $a=1$, so when all is done you get a linear function of $x$, hence the name linearization.

Do you know about polar coordinates? Do you know about the Normal distribution? In what context are you asking this question, for which class is this the homework for?
