(a \cdot f)^{'} = a \cdot f^{'}

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

Wende die Quotientenregel an:

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

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

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

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

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