Hi I'm learning about The chainrule, and I understand how to apply the chain rule on various problems, but there is a problems I don't understand how works: 1) The book I'm reading writes acceleration as
a=v*(dv)/dt
And IT argues that v=ds/dt and a=dv/dt (which i understand)
So therefore by applying the chain rule we get
a=dv/ds*ds/dt =v*dv/ds.
The part i don't understand is: How did we get dv/ds by applying the chain rule? What does the derivative of Velocity with respect to distance even men? Usually it's ds/dv and not dv/ds.
a=v*(dv)/dt
