How to evaluate $\lim\limits_{s\to\infty}\log s$? I am stuck with applying limit at the following step,
limit
$$
\lim\limits_{s\to\infty}\log s.
$$
Now I am unable to do anymore steps(I cant figure out how do I  apply the limit and get a valid answer). Please help me out.
The statement $$\lim_{x\to\infty}\log x=+\infty$$

is true if and only if for each $M&gt;0$ there exists $N&gt;0$ such that whenever $x&gt;N$ we have $\log x&gt;M$. Given $M$, take $N=e^M$. Since the logarithm is an increasing function, whenever $x&gt;N=e^M$ we will have $\log x&gt;\log N=M$, thus $$\lim_{x\to\infty}\log x=+\infty$$
If you observe graph below which represents $\log(s)$ you may conclude that:

$\lim\limits_{s\to+\infty}\log s=+\infty$

$\lim\limits_{s\to-\infty}\log s$  isn't defined since $s&gt;0$
