1. The problem statement, all variables and given/known data
$$\sum_{n=1}^\infty sin(\frac{1}{n^2})$$

2. Relevant equations
For serie $$a_n$$ and $$b_n$$ if:

A = $$0 \leq a_n \leq b_n$$

if $$b_n$$ converges then $$a_n$$ converges

3. The attempt at a solution
I think that I have to use the equation (see 2) and then with

B = $$\sum_{n=1}^\infty \frac{1}{n^2}$$

I think that it is larger than A. However I need proof... Any suggestions.
