Schritte zur Lösung

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

Wende Exponentenregel an:

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

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

Wende die Kettenregel an:

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

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

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

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

Vereinfache

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

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

\frac{df}{d x} f (x) = cos (2 x)

(cos (7 x)) y^{^{'}} - 7 (tan (7 x)) y = 9 sec (7 x)
