And our denominator, we're going to have a 0 minus sine of 0. Well, that's also going to be 0, but we have that indeterminate form, we have that undefined 0 over 0 that we talked about in the last video. So maybe we can use L'Hopital's Rule here. In order to use L'Hopital's Rule, then the limit as x approaches 0 of the derivative of this function over the derivative of this function needs to exist. So let's just apply L'Hopital's Rule and let's just take the derivative of each of these and see if we can find the limit. If we can, then that's going to be the limit of this thing. So this thing, assuming that it exists, is going to be equal to the limit as x approaches 0 of the derivative of this numerator up here.
