| Dec 17, 2013 at 0:20 | comment | added | Raymond Manzoni | @MikeSpivey: here too simpler answers could be given to evaluate directly $\;\displaystyle\sum_{n=1}^\infty \frac{H_{2n}}{n^2}$ or possibly $\;\displaystyle\sum_{n=1}^\infty \frac{H_{2n+1}}{n^2}$ (but these things take much time so...). You were indeed lucky ! | |

| Dec 16, 2013 at 16:44 | comment | added | Raymond Manzoni | You are right @ALGEAN I had two signs wrong since the odd terms had to cancel (corrected). | |
| Dec 16, 2013 at 16:42 | history | edited | Raymond Manzoni | CC BY-SA 3.0 | two wrong signs... |
| Dec 16, 2013 at 16:15 | comment | added | user91500 | If we let $n=2m$ then $S(1)-S(-1)=0$. | |
| Dec 16, 2013 at 16:10 | comment | added | user91500 | Thanks very much. Why $S(1)-S(-1)=2\sum_{m=1}^\infty \frac{H_{2m}}{(2m)^2}$? | |
