The text is giving me steps on how to do it but I don't get what's it is asking. The equation is (v^-.5)v'=k where v= volume Then says we consider the chain rule together with elementary antiderivative formulas to determine an antiderivative with respect to t of (v^-.5)v' I haven't learned integrals yet. I'm exactly sure i'm even looking for. I don't really need an answer but explanation how chain rule can applies here. Since V is a function of t, do I expand v' to v'*dv/dt?
