if Sn is the nth partial sum of the harmonic series, show that e^Sn &gt; n+1. Why does this imply that the harmonic series is di
yanalaym [24]
S_n=\displaystyle\sum_{k=1}^n\frac1k

You have

\ln e^{S_n}=S_n\ln e=S_n

so showing that e^{S_n}>n+1 amounts to the same as showing that S_n>\ln(n+1).

As n\to\infty, you have \ln(n+1)\to\infty. By comparison, then, it follows that S_n\to\infty at a faster rate, which means S_\infty must diverge.
