| May 19, 2019 at 6:19 | comment | added | Maxime Ramzi | @AknazarKazhymurat well $2\leq n$ and $n=1\leq 2$ so $1=2$ | |
| May 19, 2019 at 5:26 | comment | added | user74900 | @Max what is your argument? More generally, how do we evaluate it to any value? | |
| May 18, 2019 at 19:14 | comment | added | Maxime Ramzi | Somewhat surprisingly (?), I can also evaluate this to be $2$. It of course follows that $1=2$ (in the context "$n:\{x: \mathbb{N}\mid x$ is the largest integer $\}$") | |
| May 9, 2019 at 18:23 | comment | added | Vaelus | Assuming $lim_{n \to \infty} \frac{n}{1}$ exists, this answer has the highest "difficulty to prove existence/difficulty to evaluate" ratio. | |
| May 8, 2019 at 12:43 | comment | added | user74900 | What can I say then? The point still stands. | |
| May 8, 2019 at 12:43 | comment | added | Najib Idrissi | The question has never been edited, as far as I can tell. | |
| May 8, 2019 at 12:41 | comment | added | user74900 | @NajibIdrissi yes, that is a reasonable interpretation. Was not specified at the time I was answering though. | |
| May 8, 2019 at 12:40 | comment | added | Najib Idrissi | I think the question is implicitly asking for examples were existence is hard but still true. This is more like an example you would show to undergrads to make a point about rigor. | |
| May 8, 2019 at 11:36 | comment | added | user74900 | I am not quite sure why this got down-votes. Among all the answers that I can see right now, this appears to have the highest "difficulty to prove existence/difficulty to evaluate" ratio. Or is it really easy to prove there is the largest positive integer? | |
