The application is actually reasonably straightforward. What L'Hopital's Rule tells us is that if we have, and I'll do it in abstract form first, but I think when I show you the example, it will all be made clear. If the limit as x approaches c of f of x is equal to 0, and the limit as x approaches c of g of x is equal to 0, and the limit as x approaches c of f prime of x over g prime of x exists and it equals L, then all of these conditions have to be met. This is the indeterminate form of 0 over 0, so this is the first case. Then we can say that the limit as x approaches c of f of x over g of x is also going to be equal to L. This might seem a little bit bizarre to you right now, and I'm actually going to write the other case, and then I'll do an example. We'll do multiple examples, and the examples are going to make it all clear. This is the first case, and the example we're going to do is actually going to be an example of this case.
