Can L'Hopital's Rule Be Used for Limits to Infinity?

Click For Summary
SUMMARY

L'Hôpital's Rule can indeed be applied to find limits as x approaches infinity by substituting u = 1/x, transforming the limit into one that approaches 0. This method allows for the evaluation of limits that initially present indeterminate forms. The discussion emphasizes the importance of understanding the substitution technique to effectively utilize L'Hôpital's Rule in these scenarios.

PREREQUISITES
  • Understanding of L'Hôpital's Rule

I understand the use of this rule for the limit as x goes to 0, but not for the limit as x goes to infinity. Can this rule be used to find limits to infinity? How?

I have googled this but couldn't find a good explanation.

You can substitute u =1/x, and find the limit as u goes to 0.
 
Thanks!
