In this lesson, we will learn how to determine whether an alternating series is convergent or divergent using the alternating series test.
Q1:
The alternating series test does not apply to the series ∞(−1)𝑛𝑛+1. What is the reason?
Q2:
Is the series ∞(−1)(𝑛)cos an alternating series?
Q3:
Determine whether the series ∞𝑛𝜋𝑛cos converges or diverges.
