derivative f(x)= 1/(x+2)

Lösung

ableitung von

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

Lösung

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

Schritte zur Lösung

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

Wende Exponentenregel an:

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

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

Wende die Kettenregel an:

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

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

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

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

Vereinfache

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