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. The other case is if the limit as x approaches c of f of x is equal to positive or negative infinity, and the limit as x approaches c of g of x is equal to positive or negative infinity, and the limit of, I guess you could say the quotient of the derivatives exists, and the limit as x approaches c of f prime of x over g prime of x is equal to L, then we can make this same statement again. Then we can make this exact same statement. Let me just copy that out.
