Lösung

\frac{d}{d x} (\frac{1}{x ^{2} - 9})

- \frac{2 x}{( x ^{2} - 9 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{1}{x ^{2} - 9})

Wende Exponentenregel an:

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

= \frac{d}{d x} ((x^{2} - 9)^{- 1})

Wende die Kettenregel an:

- \frac{1}{( x ^{2} - 9 ) ^{2}} \frac{d}{d x} (x^{2} - 9)

= - \frac{1}{( x ^{2} - 9 ) ^{2}} \frac{d}{d x} (x^{2} - 9)

\frac{d}{d x} (x^{2} - 9) = 2 x

= - \frac{1}{( x ^{2} - 9 ) ^{2}} \cdot 2 x

Vereinfache

- \frac{1}{( x ^{2} - 9 ) ^{2}} \cdot 2 x : - \frac{2 x}{( x ^{2} - 9 ) ^{2}}

= - \frac{2 x}{( x ^{2} - 9 ) ^{2}}

\int cos^{2} (9 x) d x
