→ wickeday :M test應該可以吧? 感覺會被k^(-3/2) bound住 04/26 17:24
→ keroro321 :gn(x)=Σ(k=1->n) x/(1+(k^2)(x^2)) ?? 04/26 19:31
→ keroro321 :it doesn't converge uniformly near 0 . 04/26 19:33
→ keroro321 :for any a>0 ,this sequence of functions converges 04/26 20:07
→ keroro321 :uniformly on [a,∞) but not on (0,∞) 04/26 20:07
