Limits at Infinity

Learn how to find limits as x approaches infinity. We discuss the three cases with some examples in this free math video tutorial by Mario’s Math Tutoring.

0:22 Formula for the limit as x approaches infinity
0:37 Example 1 looks at when the limit approaches 0
0:58 How to quickly tell the limit by analyzing the powers of x in the numerator and denominator
1:59 How to show more rigorously that the limit is zero
3:25 Example 2 looks at when the limit is the ratio of the coefficients
6:17 Example 3 looks at when the limit goes to infinity (no limit)
6:20 3 Possible scenarios looking at the numerator and denominators highest degree.
