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. Then this again. Edit, copy, and then let me paste it. In either of these two situations, just to make sure you understand what you're looking at, this is a situation where if you just tried to evaluate this limit right here, you're going to get f of c, which is 0, or the limit as x approaches c of f of x over the limit as x approaches c of g of x, and that's going to give you 0 over 0.
