derivative of (36/(x^2+2))

Lösung

\frac{d}{d x} (\frac{36}{x ^{2} + 2})

Lösung

- \frac{72 x}{( x ^{2} + 2 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{36}{x ^{2} + 2})

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= 36 \frac{d}{d x} (\frac{1}{x ^{2} + 2})

Wende Exponentenregel an:

\frac{1}{a} = a^{- 1}

= 36 \frac{d}{d x} ((x^{2} + 2)^{- 1})

Wende die Kettenregel an:

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

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

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

= 36 (- \frac{1}{( x ^{2} + 2 ) ^{2}} \cdot 2 x)

Vereinfache

36 (- \frac{1}{( x ^{2} + 2 ) ^{2}} \cdot 2 x) : - \frac{72 x}{( x ^{2} + 2 ) ^{2}}

= - \frac{72 x}{( x ^{2} + 2 ) ^{2}}
