Hi
I've just been reading something which is essentially how to work out what the deriviative of y=b^x is.
Basically the explanation gets to the point which I understand and says
\frac{dx}{dy} = \frac{1}{yln(b)}
It then says because of the chain rule you can simply flip this to get
\frac{dy}{dx} = yln(b)
I have used the chain rule and thought I understood it but perhaps I don't because I don't see how the chain rule let's you do the 'flip' just described.
Any comments greatly welcomed
Kind regards
