derivative of 4/((1+2x^2))

Lösung

\frac{d}{d x} (\frac{4}{( 1 + 2 x ) ^{2}})

Lösung

- \frac{16}{( 1 + 2 x ) ^{3}}

Schritte zur Lösung

\frac{d}{d x} (\frac{4}{( 1 + 2 x ) ^{2}})

Entferne die Konstante:

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

= 4 \frac{d}{d x} (\frac{1}{( 1 + 2 x ) ^{2}})

Wende Exponentenregel an:

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

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

Wende die Kettenregel an:

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

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

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

= 4 (- \frac{2}{( 1 + 2 x ) ^{3}} \cdot 2)

Vereinfache

4 (- \frac{2}{( 1 + 2 x ) ^{3}} \cdot 2) : - \frac{16}{( 1 + 2 x ) ^{3}}

= - \frac{16}{( 1 + 2 x ) ^{3}}
