1. The problem statement, all variables and given/known data Using the comparison test determine if the infinite series for sin(3/n^2) converges or diverges. 3. The attempt at a solution Well... these are pretty straight forward, and it's pretty obvious that this is convergent, but I'm having trouble applying the comparison test to a trig function. Can we say that: sin(3/n^2) < sin(1/n) which converges?
