. The series is divergent. To see this, first observe that the series ∑ 1/kn for n = 1 to ∞ is divergent for any integer k ≥ 2.
Now, if we pick a large integer for k, say k > 100, then for nearly all integers n it will be true that 1 > cos(n) > 1/k. Therefore, since ∑ 1/kn is divergent, ∑ cos(n)/n must also be divergent The *summation* is divergent, but the individual terms converge to the number 0.<span>by comparison test since cosn/n <= 1/n is convergent
and 1/n is divergent by harmonic series
so the series is conditionally converget </span>
Answer:
The answer is:
Option 4; (14+ 9) 4 is twice as much as(14 + 9) 2
Thanks
Answer:
69.08m
calculate the circumstances :
2×r×pi
11×2×3.14
=22×3.14
=69.08m
Each balloon string is 6ft , 6ft translates to two yards he’ll need 114 yards.
The answer is 32 because there are 5 in the actual one
