And it's a more constrained version of the general case we've been looking at, but it's still very powerful and very applicable. And the reason why we're going to go over this special case is because its proof is fairly straightforward and will give you an intuition for why L'Hospital's Rule works at all. So the special case of L'Hospital's Rule is a situation where f of a is equal to 0, f prime of a exists, g of a is equal to 0, g prime of a exists. If these constraints are met, then the limit as x approaches a of f of x over g of x is going to be equal to f prime of a over g prime of a. So it's very similar to the general case, it's a little bit more constrained. We're assuming that f prime of a exists, we're not just taking the limit now. We're assuming f prime of a and g prime of a actually exist.
