(\partial)/(\partial x)((x^2+2y)/(x^3-y^2))

Lösung

\frac{\partial}{\partial x} (\frac{x ^{2} + 2 y}{x ^{3} - y ^{2}})

\frac{- x ^{4} - 6 x ^{2} y - 2 x y ^{2}}{( x ^{3} - y ^{2} ) ^{2}}

Wende die Quotientenregel an:

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

= \frac{\frac{\partial}{\partial x} ( x ^{2} + 2 y ) ( x ^{3} - y ^{2} ) - \frac{\partial}{\partial x} ( x ^{3} - y ^{2} ) ( x ^{2} + 2 y )}{( x ^{3} - y ^{2} ) ^{2}}

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

\frac{\partial}{\partial x} (x^{3} - y^{2}) = 3 x^{2}

= \frac{2 x ( x ^{3} - y ^{2} ) - 3 x ^{2} ( x ^{2} + 2 y )}{( x ^{3} - y ^{2} ) ^{2}}
