Well, this first part, I will do it in orange, this first part would just be cosine of x squared plus five times cosine of x. So that's that circle right over there. Let me close the cosine right over there. And then times the derivative with respect to x, times the derivative with respect to x of all of this again, of x squared plus five times cosine of x. And then I would close my brackets. And of course, I wouldn't be done yet. I have more derivative taking to do.
