Homework Statement
[tex]\sum_{n=2}^{\infty}sin(\frac{\pi*n}{2})/{2}[/tex]I don't have a solution, and wondered if the execution is correct.
The Attempt at a Solution
I thought that one can use comparison test where; [tex]\sum b_n[/tex]= [tex]\frac{1}{n^{1/2}}[/tex].
Since p<1 ---> divergent. But many of the students says it converges. Some suggestions?
We know that the series is alternating, and if I use its test I get that it converges. Reckon that perhaps the fault lies there?
