(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{\partial}{\partial y} ( y ) ( 1 + x ^{2} y ^{2} ) - \frac{\partial}{\partial y} ( 1 + x ^{2} y ^{2} ) y}{( 1 + x ^{2} y ^{2} ) ^{2}}

\frac{\partial}{\partial y} (y) = 1

\frac{\partial}{\partial y} (1 + x^{2} y^{2}) = 2 x^{2} y

= \frac{1 \cdot ( 1 + x ^{2} y ^{2} ) - 2 x ^{2} yy}{( 1 + x ^{2} y ^{2} ) ^{2}}

1 \cdot (1 + x^{2} y^{2}) - 2 x^{2} yy = 1 - y^{2} x^{2}

= \frac{1 - y ^{2} x ^{2}}{( 1 + y ^{2} x ^{2} ) ^{2}}
