Worked example: sequence convergence/divergence
WebWe know that the series converges, but we need to determine whether it converges absolutely or not. In other words, we must determine if X∞ n=1 (−1) n n 1+n2 = X∞ n=1 n 1+n2. converges or not. To see that this series diverges, limit compare with the harmonic series P 1 n, which we know diverges: lim n→∞ n 1+n2 1 n = lim n→∞ n2 1 ...
