a lu'en Let eq of Nomal ( y-k=-frac{d y}{d y}(x-k) ) grum ( int frac{1 frac{d x}{d y}+k}{sqrt{left(frac{d x}{d y}right)^{2}+1}}= ) ( n^{2}left(frac{d x}{d y}right)^{2}+x^{2}+2 n k frac{d x}{d y}=k^{2}left(frac{d x}{14}right)^{2} ) ( +k^{2} ) So eq of curve ( frac{x^{2}}{m^{2}}+frac{2 x y}{m}=frac{y^{2}}{m^{2}} ) ( operatorname{sen} x^{2}+2 x y m=y^{2} ) ( m=frac{y^{2}-x^{2}}{2+y} ) ( frac{d y}{d x}=frac{y^{2}-x^{2}}{2 x y} )
