So when you write it like this, it starts to get into a form, you're like, oh, I can see how the power rule could apply there. So this thing is just pi squared times x to the negative 2 3rd power. So actually let me delete this. So this thing can be rewritten, this thing can be rewritten as pi squared times x to the negative 2 3rd power. So now let's take the derivative of each of these, each of these pieces of this expression. So we're gonna take, we wanna evaluate what g prime of x is. So g prime of x is going to be equal to, you could view it as a derivative with respect to x of seven sine of x.
