This video introduces limits at infinity, that is, limits as x goes to plus or minus infinity. This video begins by using the squeeze theorem to show why (sin x)/x goes to 0. It then continues to use one of the key principles of evaluating limits at infinity: divide all terms by the highest power in the denominator. It also gives two examples that show how to evaluate limits at infinity in polynomials. Squeeze Theorem: • The Squeeze Theorem ADA-compliant subtitles/captions
