Lösung

ableitung von

(arctan (9 x))^{2}

Lösung

\frac{18 arctan ( 9 x )}{81 x ^{2} + 1}

Schritte zur Lösung

\frac{d}{d x} ((arctan (9 x))^{2})

Wende die Kettenregel an:

2 arctan (9 x) \frac{d}{d x} (arctan (9 x))

= 2 arctan (9 x) \frac{d}{d x} (arctan (9 x))

\frac{d}{d x} (arctan (9 x)) = \frac{9}{81 x ^{2} + 1}

= 2 arctan (9 x) \frac{9}{81 x ^{2} + 1}

Vereinfache

2 arctan (9 x) \frac{9}{81 x ^{2} + 1} : \frac{18 arctan ( 9 x )}{81 x ^{2} + 1}

= \frac{18 arctan ( 9 x )}{81 x ^{2} + 1}
