Jan7 accepted Show that there's a bijective $f: \mathbb{N} \to \mathbb{N}$ such that $\sum_{n=1}^{\infty} (-1)^{f(n)}\ln\frac{f(n)+1}{f(n)}=\ln 2010$ Jan5 accepted Bounding a series from above using the integral test Jan4 accepted Convergence of $\sum \limits_{n=1}^{\infty} (1-\frac{\sin a_{n}}{a_{n}})$ when $\sum \limits_{n=1}^{\infty} a_{n}$ converges
