derivative of 4/(11-x)

Lösung

\frac{d}{d x} (\frac{4}{11 - x})

Lösung

\frac{4}{( 11 - x ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{4}{11 - x})

Entferne die Konstante:

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

= 4 \frac{d}{d x} (\frac{1}{11 - x})

Wende Exponentenregel an:

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

= 4 \frac{d}{d x} ((11 - x)^{- 1})

Wende die Kettenregel an:

- \frac{1}{( 11 - x ) ^{2}} \frac{d}{d x} (11 - x)

= - \frac{1}{( 11 - x ) ^{2}} \frac{d}{d x} (11 - x)

\frac{d}{d x} (11 - x) = - 1

= 4 (- \frac{1}{( 11 - x ) ^{2}} (- 1))

Vereinfache

4 (- \frac{1}{( 11 - x ) ^{2}} (- 1)) : \frac{4}{( 11 - x ) ^{2}}

= \frac{4}{( 11 - x ) ^{2}}
