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. So the second derivative of y with respect to x. And what do we get here on the right-hand side? Well, we can apply the product rule.
