HW6
1. Define a_{2k-1}= -1/sqrt{k} , a_{2k} = 1/sqrt{k}+1/k. Show that
\Pi_{k=1}^{\infty}(1+a_k} cpnverges , but \sum_{k=1}^{\infty} diverges.
From the expansions
\pi cot \pi z -1/z = \sum+{k=1}^{\infty} \frac{2z}{z62-n^2}
deduce
 a ) \sum_{k=-\indty}^{\infty}\frac{1}1+n^2}= \pi coth \pi
b) \sum_{n=1}^{\infty} \frac{1}{n^2}= \frac{\p^6}{6}.
