P1 (a) Use the integral test to study the convergence of the series
In(n)
n²
n=2
Edit: It previously said log(x) instead of ln(x).
(b) Use the alternating test to study the convergence of the series
8
2n
Σ(-1)^2
1) 201
n!
n=1
(c) Study the convergence of the following series
n=1
(-1)+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.
