nice timing! lol we almost uploaded the response at the same time! anyway thanks a lot for sparing your time for my question! :)

I found out why! It is in fact, chain rule. if we differentiate left and right side by t dz/dt = dz/dy X dy/dt , dy/dt=y'=z...

i definitely agree with what you guys said and that was the reason why I was asking this here. Then do you think it's just a typo? I thought i mistook something.

sorry but, that's not what I'm asking.. I mean the second term in the equation.

while solving differential equations, I got a bit confused with chain rule problem. The solution says below yprime = z then y double prime = z (dz/dy) = z prime but I don't understand why the differentiation of z is in that form. Please help...
