Determine whether the sequence converges or diverges. If it converges, find the limit. (If the sequence 2021 diverges, enter DIVERGES.) (a) an = 7. [-13 F lim an Deter conv (b ) bp = _ cos (n) 37 lim b= n -+ 0o Justify your answer. O Use L'Hopital's Rule to find a limit that does not have an indeterminate form. O Use the Power Rule on the numerator cosine. O Use the Quotient Rule to find the limit of each of the numerator and the denominator. O Use the Squeeze Theorem by considering the range of cosine
