Schritte zur Lösung

\frac{d}{d x} (\frac{x}{( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{3}{2}}})

Wende die Quotientenregel an:

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

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

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

\frac{d}{d x} ((x^{2} + y^{2} + z^{2})^{\frac{3}{2}}) = 3 x (x^{2} + y^{2} + z^{2})^{\frac{1}{2}}

= \frac{1 \cdot ( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{3}{2}} - 3 x ( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{1}{2}} x}{( ( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{3}{2}} ) ^{2}}

Vereinfache

\frac{1 \cdot ( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{3}{2}} - 3 x ( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{1}{2}} x}{( ( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{3}{2}} ) ^{2}} : \frac{- 2 x ^{2} + y ^{2} + z ^{2}}{( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{5}{2}}}

= \frac{- 2 x ^{2} + y ^{2} + z ^{2}}{( x ^{2} + y ^{2} + z ^{2} ) ^{\frac{5}{2}}}
