(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

using the squeeze theorem:

lim cosn / sqrt(n)

n -> infinity

2. Relevant equations

cos/n/sqrt(n) and 1/sqrt(n)

3. The attempt at a solution

I just have a question about the squeeze theorem.

From my understanding, when using the squeeze theorem for these time of sequence calculus problems, I am always going to have the original equation in the middle?

also, why does one side of the squeeze theorem need to be negative?

this sequence approaches 0.

heres the work:

-1/sqrt(n) <= cosn/sqrt(n) <= 1/sqrt(n)

and, if this happened to be sin instead of cosine, would i just put 0 on both sides of the <= instead of the equations.

thanks alot.
