comment How does one easily compute the limit of $a_n=(n\cdot \ln(\frac{n+1}{n}))^n$?
As $n$ goes to what?

comment $y''=(y')^{3} e^{y}$, some easy way to solve this non-linear differential equation?
Did you tried using Wolfram Alpha? It can also shows you a step-by-step solution.

comment Question about a lemma on continuity
@Arturo Sorry. That was a translation mistake. In German, one says "stetig" to say "continuous". stetig and steady are false friends...

comment Given the cartesian coordinates of four points, how to calculate the interection of two lines they form?
@J.M. Oh yeah. That looks good. THank you! BTW, is there a solution that use the $r,\vartheta$ representation instead?

@J.M. Of course. This possibility is ruled out.

comment Defining division by zero
@picakhu You are going to run into problems when calculating limits. Just consider $\lim_{n\to0}\frac{2n}n$. Using your method, one gets $\frac{\infty_0}{\infty_0}=1$, while one gets $\frac21=2$ using the definition of limits.
