Homework Statement
Show that
[tex]\frac{1}{x} \ln \frac{x+1}{x-1} = \sum_0^\infty \frac{2x^{2n}}{2n+1}[/tex].
2. The attempt at a solution
I tried to use the relation
[tex]\frac{1}{1+x} = \frac{d}{dx}\ln (1+x)[/tex]
and expand as a geometric series, but this did not lead anywhere since I then ended up with an alternating series.
Anyone got any ideas of where to start?
