comment Does $\lim_{x\rightarrow 0}\frac{c}{|x|}$ exist?
Your calculus textbook does warn you about the case $g(x)\neq 0$ so why consider it?

comment Is the extra condition in this definition superfluous?
@Srivatsan if it is not finite then we cannot conclude that $0\cdot c =0$ and the argument won't stand.

comment Is the extra condition in this definition superfluous?
@Srivatsan Yes. So I guess this person's argument is right. The statement should be that order is the minimum $n$ for which the stated limit is non zero and finite.

comment Is the extra condition in this definition superfluous?
@Srivatsan why not? It uses the fact that the limit for $k=n+1$ is $c\neq 0$ to show that the limit would be zero for every $k\leq n$. Re: additional comment, I agree, specially after seeing this argument. I need a confirmation that nothing fishy is going on as this refutes an argument presented in two books.
