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

Lösung

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

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

Schritte zur Lösung

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

Behandle

als Konstante

Wende die Quotientenregel an:

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

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

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

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

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

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

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

y^{^{'''}} - 2 y^{^{''}} - y^{^{'}} + 2 y = 0
