ok so i have the problem:
If and , find by implicit differentiation.
so i differentiate both sides and get -1/x^2 + -y'/y^2 = 0
then i solve for y' and get y'=-y^2/x^2
this is wrong but i do not know where i went wrong..... im thinking it has to do with the derivative of the 1/y.
could i get some advice please =)
