Turn in the following problems: Below are several sequences, each paired with a graphical representation. Explain if each of the sequences converge or diverge using both the given sequence and its graphical representation. (a)
a_(n)=(cos(n))/(n)(b)
b_(n)=(-1)^(n) ((-1)^(n))/(n)(c)
c_(n)=(-1)^(n) (1)/(n)
