The last step in the second line is not completely clear to me. Could you please elaborate why this holds?

@francis-jamet We showed that the limit exists just as Srivatsan described.

@SrivatsanNarayanan Thank you! By the way, is it clear, which proof I refer to?

comment Easy proof, that $\rm e\notin \mathbb Q$
@anon Fixed the first one. The second proof is not difficult, but takes too much time. That's all.

comment Easy proof, that $\rm e\notin \mathbb Q$
@Yuval That is actually how we did this. The problem is, that the students in my class don't like proofs containing too many “It is easy to see that...”s. The proof using this strategie filled one A4 page in the script and took 20 minutes for me to explain. (Although it is quite easy if you think about it).

comment Database for mathematical syntax
@3Sphere Such a reference is quite useful if you see a formula in the Internet or in a paper where the author sees no reason to include a syntax definition. So even a lookup with many definitions is great, as one can often tell the right one from the context.

There is a simple way: Just use Wolfram Alpha
