Used To Be Able To Find The Limit And Confirm It. I Really Don't Know How To Use The Sandwich Theorem.
I just don't understand how and when to use it, for example:
lim x-> infinity (1-cosx) / x^2
in the book, it gives and example ofsinx / x which i get up to some point, and then i lose myself :/
Thank you in advance
i had the same problem, until i watch this on you tube.
The person explains clearly what the sandwhich Theorem (or the Squeeze Theorem which the person calls it) is.
and shows a good example of the Proof: lim (sin x)/x = 1
