I do! But I coudn not see why I had to use the chain rule here. (I see it clearer when I have ie. (cos(x))^sin(x)) but I do now! I’m not used to the physics notation of derivatives. But that was helpful, so thanks a lot.

Summary:: According to Yale’s University PHYS: 200: v*(dv/dt) = d(v^2/2)/dt Could someone explain how has he reached that conclusion? He claims to be some standard derivation rules, but I can’t find anything about it. As much as I can tell: (dv/dt)* v = v’ * v = a* v thanks! [Moderator's...
