Question
P1 (a) Use the integral test to study the convergence of the series In(n) n² n=2 Edit: It previously said log(r) instead of ln(x). (b) Use the alternating test to study the convergence of the series 8 Σ(-1)" n=1 (c) Study the convergence of the following series n=1 2n n! (−1)n+1 2n + (−1)n Is it absolutely convergent? Remember to justify all the hypothesis needed to use the test in both parts of this exercise.
