I entered the following into the search box and came up empty: \lim_{n\to\infty}(1+\frac xn)^n

I'd like to know whether someone has posted this question: How does one prove that $$ \lim_{n\to\infty}\left(1+\frac xn\right)^n = e^x\text{ ?} $$

So two questions: (1) How to search for that?; and (2) Is it there?

    $\begingroup$ Here are the results from Google for that search restricted to math.stackexchange.com. Of course, there are many ways how to write that expression; so it is possible to experiment and try different similar searches. $\endgroup$ – Martin Sleziak Apr 17 '13 at 16:39

I've found six posts on this topic, listed here.

These were found by e.g. looking through related posts; I've also searched for things like:

[limit] "\frac" is:q

with obvious changes. I didn't really use Google to browse the site this time. But using

site:math.stackexchange.com

in your Google query limits the search to MSE, which is quite useful.

Try to use Approach0.xyz:

https://approach0.xyz/search/?q=%24%5Clim_%7Bn%5Cto%5Cinfty%7D%5Cleft(1%2B%5Cfrac%7Bx%7D%7Bn%7D%5Cright)%5En%3D%3F%24&p=1
