So I'm gonna take the derivative, it's sine of something. So this is going to be, the derivative of this is going to be the sine of something with respect to something. So that is cosine of that something times the derivative with respect to x of the something. In this case, the something is our x squared. And of course, we have all of this out front, which is the three times sine of x squared, and I could write it like this, squared. Alright, so we're getting close. Now we just have to figure out the derivative with respect to x of x squared, and we've seen that many times before.
