Thread: Find the limit of the sequence

Please help!
Use the squeezing theorem to find the limit of the sequence

Hello,

First of all, you can divide the numerator & the denominator by n

-->

Now, the squeeze theorem.

(these are all )

-1<sin(n)<1
-1<cos(n)<1 --> -3<3cos(n)<3

---> -1-3<sin(n)+3cos(n)<1+3

Hence,

Moo, u r alwasy so helpful and...so fast!
Can't thank u enough
