Series: Divergent or Convergent ?

Click For Summary
SUMMARY

The series ∑( e^(6pi*n) sin^2(4pi*n) ) from -infinity to infinity is divergent. The evaluation of sin(4πn) for integer values of n results in zero, as sin(4πn) equals zero for all integer n. Consequently, the term sin^2(4πn) also equals zero, leading to the conclusion that the series does not converge to a finite value.

How can I tell if the following series is Divergent or Convergent:

∑( e^(6pi*n) sin^2(4pi*n) ) the sum limits are from -infinity to infinity
