1. The problem statement, all variables and given/known data does it converge absolutely, converge conditionally, or diverge? heres the equation: http://img219.imageshack.us/img219/4645/untitled29fy.jpg 2. Relevant equations sin(pi/n) 3. The attempt at a solution looks like the sin equation converges to zero. i think this is an alternating series, but i'm not sure if this part converges or diverges? thanks for any help here.
