derivative of ((x+5/(x^2+2))^2)

Lösung

\frac{d}{d x} ((\frac{x + 5}{x ^{2} + 2})^{2})

\frac{2 ( x + 5 ) ( - x ^{2} - 10 x + 2 )}{( x ^{2} + 2 ) ^{3}}

Schritte zur Lösung

\frac{d}{d x} ((\frac{x + 5}{x ^{2} + 2})^{2})

Wende die Kettenregel an:

2 \cdot \frac{x + 5}{x ^{2} + 2} \frac{d}{d x} (\frac{x + 5}{x ^{2} + 2})

= 2 \cdot \frac{x + 5}{x ^{2} + 2} \frac{d}{d x} (\frac{x + 5}{x ^{2} + 2})

\frac{d}{d x} (\frac{x + 5}{x ^{2} + 2}) = \frac{- x ^{2} - 10 x + 2}{( x ^{2} + 2 ) ^{2}}

= 2 \cdot \frac{x + 5}{x ^{2} + 2} \cdot \frac{- x ^{2} - 10 x + 2}{( x ^{2} + 2 ) ^{2}}

Vereinfache

2 \cdot \frac{x + 5}{x ^{2} + 2} \cdot \frac{- x ^{2} - 10 x + 2}{( x ^{2} + 2 ) ^{2}} : \frac{2 ( x + 5 ) ( - x ^{2} - 10 x + 2 )}{( x ^{2} + 2 ) ^{3}}

= \frac{2 ( x + 5 ) ( - x ^{2} - 10 x + 2 )}{( x ^{2} + 2 ) ^{3}}

\frac{d ^{2}}{d x ^{2}} (e^{\frac{6}{x}})
