How would I solve the limit for this sequence.
[n^(2)]*[1-cos(2.4/n)]
I used L'Hopital's rule by putting n^(-2) in the bottom, but I got the wrong answer of -1.44 in the end. Please help, thanks!
what's your name.
i think i'm in your class.
I'm having the same problem. Hopital isn't the way to solve this problem though.
