Working in wee hours really exhausts me.
Recently I have left over many problems at hand..., especially those problems with unreasonable difficulty.

As an example, you can, though not encouraged, try to show that $\sum_{n=1}^\infty \frac{1}{n}\left(\frac{2+\sin n}{3}\right)^n$ converges,

	Problem in Homework set 10. 1. Prove that if $\sum x_n$ converges, then $\prod (1+ x_n)$ converges if and only if $\sum x_n^2$ converges. 2. Prove that if $\sum x_n^2$ converges, then $\prod (1+ x_n)$ converges if and only if $\sum x_n$ converges.
