And I'll give you my little aside, like I always do, the quotient rule, if you ever forget it, it can be derived from the product rule. And we have videos there, because the product rule's a little bit easier to remember. But what I can do is just say, look, dy dx, if y is just u of x over v of x, I'm just gonna restate the quotient rule. This is going to be, this is going to be the derivative of the function in the numerator. So d dx of u of x times the function in the denominator, times v of x, minus, minus, I'll do the, minus the function in the numerator, u of x, times the derivative of the function in the denominator, times d dx, v of x, and we're almost there, and then over, over, the function in the denominator squared. The function in the denominator squared. So this might look messy, but all we have to do now is think about, well, what is the derivative of u of x?
