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?

comment What kind of a mean value is this?
@user3085931 That it is an average means that some actual values could (and likely will) be higher and some could (and likely will) be lower. Average must be in the middle, so it cannot be some will match exactly and others will be all higher or all lower. You should have a mix.

comment What kind of a mean value is this?
@user3085931 I am not familiar with your process's terms, but if I had to explain to someone in English what that quantity was, this is the term I would use.

comment Understanding Integral
Generally, $\int dF(x) = \int F'(x) dx$ which is sometimes written as $\int f(x) dx$ where $f(x) = F'(x)$. But I've never seen $\int dF(x) = \int F(x)dx$.
