Hello,
I have two question:
Firstly,
I got this problem:
I should determine weather the series converges.
I thought about using leibinz test but I don't know how to prove that
is monotonlly decreasing.
The second qeustion I would like to ask is, if I don't know about a series if its positive, can I use d'almbert ratio test in this way:
and if for example for the none positive series I show in this way that the series diverges is this a legit proof?
Thank you!
