And then we can hopefully find our second derivative of y with respect to x. And to help us there, actually, let me rewrite this. And I always forget the quotient rule, although it might be a useful thing for you to remember. But I could rewrite this as a product, which will help me at least. So I'm gonna rewrite this as the derivative of y with respect to x is equal to x times y to the negative one power, y to the negative one power. And now, if we wanna find the second derivative, we apply the derivative operator on both sides of this equation, derivative with respect to x. And our left-hand side is exactly what we eventually wanted to get.
