So here we are not done. We need to take this and multiply it times g prime of x. And let me write this down. G prime of x, what would that be? Well, the derivative of sine of x with respect to x, well, that's just going to be cosine of x. Cosine, cosine of x. Cosine of x. So in this example right over here, the derivative is going to be, let's see if I can squeeze it in over here, it's gonna be one over sine of x, which is this part, times cosine of x. So let me write it down.
