O limita cu sirul armonic
Sa se calculeze \( \lim_{n\to\infty} e^{H_{n+1}}-e^{H_{n}} \), unde \( H_{n}=1+\frac{1}{2}+\ldots +\frac{1}{n} \) este sirul armonic.
An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says “You’re all idiots”, and pours two beers.
