derivative of (3-x^2/(2x+2))

Lösung

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

- \frac{x ^{2} + 2 x + 3}{2 ( x + 1 ) ^{2}}

Schritte zur Lösung

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

Wende die Quotientenregel an:

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

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

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

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

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

Vereinfache

\frac{( - 2 x ) ( 2 x + 2 ) - 2 ( 3 - x ^{2} )}{( 2 x + 2 ) ^{2}} : - \frac{x ^{2} + 2 x + 3}{2 ( x + 1 ) ^{2}}

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

\frac{d}{d x} (\frac{3 x}{x ^{2}})

\int x^{2} e^{- \frac{x}{4}} d x

\frac{d}{d x} (cos^{2} (8 x))
