In this video, I'm just going to show you what L'Hopital's Rule says and how to apply it. It's fairly straightforward. It's actually a very useful tool sometimes if you're in some type of a math competition. They ask you to find a difficult limit that when you just plug the numbers in, you get something like this. L'Hopital's Rule is normally what they are testing you for. In a future video, I might prove it, but that gets a little bit more involved. The application is actually reasonably straightforward.
