 Question 579910: Determine if the following series are convergent of divergent. If the series is geometric find the sum as well: [cos(n*pi/3)] / n factorial at n =1 to infinity Thank you so much! Answer by KMST(1874)   (Show Source): You can put this solution on YOUR website!It is not a geometric series. , and (n factorial) grows without bounds , so converges to zero
