I have 4 problems left and the questions says I have to test them for converge or divergence.
Here are the problems

for 25, I want to take the limit as n goes to infinity however I get (-1)^[itex]\infty[/itex] and stuck there
for 27, similar problem how do i take the limit of cos([itex]\infty[/itex])
for 43 i have no idea
for 45, I feel like i should use lhr, but i can't take the derivative of n!
Please try and explain it to me, as I already have the answers I just want to learn
