\frac{- x + 6}{2 ( 2 - x ) 2 - x}

Schritte zur Lösung

\frac{d}{d x} (\frac{x + 2}{2 - x})

Wende die Quotientenregel an:

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

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

\frac{d}{d x} (x + 2) = 1

\frac{d}{d x} (2 - x) = - \frac{1}{2 2 - x}

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

Vereinfache

\frac{1 \cdot 2 - x - ( - \frac{1}{2 2 - x} ) ( x + 2 )}{( 2 - x ) ^{2}} : \frac{- x + 6}{2 ( 2 - x ) 2 - x}

= \frac{- x + 6}{2 ( 2 - x ) 2 - x}

\frac{\partial}{\partial k} (ln (sin (\frac{x}{k})))
