Determine the convergence/divergence of the following series using the integral test:
a.) ∑= (1)/n(In(n))^2 (Upper limit of sigma is ∞ ,and the lower limit of sigma is n=2)
b.) ∑ (n-4)/(n^2-2n+1) (Upper limit of sigma is ∞ and the lower limit of the sigma is n=2
c.)∑ (n)/(n^2+1) (Upper limit of sigma ∞ and the lower limit sigma is n=1)
d.) ∑ e^-n^2 (Upper limit of sigma ∞ and the lower limit sigma
is n=1)
