Best ResponseYou've already chosen the best response.1\[\LARGE 3x^{2}+3y^{2} \frac{dy}{dx}3ax=0\] this gives..finally.. \[\LARGE \frac{dy}{dx}=\frac{x(ax)}{y^{2}} \] I doubt this because im quite unsure about the derivative of 3axy,we are differentiating wrt x or y? if its x then 3ay(dx//dx) not sure..
