How do I show that [tex]\sum_1^n\frac{1}{k}[/tex] is not an integer for n>1? I tried bounding them between two integrals but that doesn't cut it. I know that [tex]\sum_1^n\frac{1}{k}=\frac{(n-1)!+n(n-2)!+n(n-1)(n-3)!+...+n!}{n!}[/tex] but I can't get a contradiction.(adsbygoogle = window.adsbygoogle || []).push({});
