Determinati functiile \( f:\mathbb{R}\to\mathbb{R} \) pentru care
\( x-F(x)=(1+x^{2})(f(x)-1) \) unde \( F:\mathbb{R}\to\mathbb{R} \) este o primitiva a lui \( f \).

Primitiva si functia intr-o ecuatie functionala
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.
