How could I find this limit? Any idea would be appreciable.

Actually, I think there is a slight error there- the " " should not be in there. Try instead and , 1 over the even integers and 1 over the odd integers.

Now, I am hoping that "It is a little bit difficult for me" does NOT mean "I really don't want to actually do anything my self" so I will make some suggestions: If , what is ? What is the cosine of that? What does that go to as n goes to infinity? If , what is ? What is the cosine of that? What does that go to as n goes to infinity?
