How do differentiate x/y^3

Question

psymon · Answer

Well, this is implicit differentiation. You would treat it like a normal derivative, but whenever you take the derivative of y, you have to mark it and keep track. Otherwise we would start this the same way, with quotient rule. You know the quotient rule?

On here I would get used to the equation editor right below the chat. It helps us work these out in a much more neat manner. So let's put up the quotient rule and then be careful from there.
