So I have two curves graphed here, and we're used to seeing things where y is a function of x, but here we have x as a function of y. In fact, we can write this top expression as being a function of y, and this second one, just to make it different, we could view this as g of y. Once again, it is a function of y. And what we're concerning ourselves with in this video is how do we find this area in this light blue color between these two curves? And I encourage you to pause the video and try to work through it. All right, so a huge hint here is we're going to want to integrate with respect to y, a definite integral where our bounds are in terms of y. So for example, this is this lower point of intersection right over here.
