Can someone please explain the steps to derive this? I've seen it everywhere, but the explanation is never given.
My confusion arises from the second line. In EVERY math book I've ever picked up, whenever you take a derivative, it is ALWAYS with respective to something, i.e y w.r.t x, or some variable w.r.t time, etc. But in this example as shown in textbooks, it seems as though they are taking a derivative, but it is not w.r.t anything. For example, instead of saying dy/dx, they would just be saying dy, which doesn't really make any sense to me. I'm confused about this.
I haven't seen a good explanation of this type of derivative yet. I attached an example. Thanks
