Question
1) Leta k = k 2 + s i n k 7 k . Which of the following inequalities is/are true for any positive integer
1) Letak=k2+sink7k. Which of the following inequalities is/are true for any positive integer k?
Select all that apply.
ak>7/k
0 ak7kk2+1 0 0 2)Letan be an infinite series. Choose the correct statements below. If an converges, then |an| converges. If |an| converges, then an converges. If an diverges, then |an| diverges. If |an| diverges, then an diverges. 3) The seriesn=1n4cos(n) converges absolutely. What does that mean? n=1n4cos(n)diverges n=1n4cos(n)converges Bothn=1cos(n) andn=1n41 There is a very high chance thatn=1n4cos(n)converges.
