# convergence of the sequence (1+1/n)^n
###### Theorem 1.
The following sequence:
$a_{n}=\left(1+\frac{1}{n}\right)^{n}$ (1)
is convergent.
###### Proof.
The proof will be given by demonstrating that the sequence (1) is:
1. 1.
monotonic (increasing), that is $a_{n}
2. 2.
bounded above, that is $\forall n\in\... | {} |

Method The nicest method I have seen is one that expresses the automaton as equation system of (regular) languages which can be solved. It is in particular nice as it seems to yield more concise expressions than other methods. Let $A= (Q,\Sigma,\delta,q_0,F)$ an NFA without $\varepsilon$-transitions. For ev... | {} |
