Lösung

\frac{d}{d x} (arctan^{t a n (x)} (x))

arctan^{t a n (x)} (x) (sec^{2} (x) ln (arctan (x)) + \frac{tan ( x )}{arctan ( x ) ( x ^{2} + 1 )})

Schritte zur Lösung

\frac{d}{d x} (arctan^{t a n (x)} (x))

Wende Exponentenregel an:

a^{b} = e^{b l n (a)}

arctan^{t a n (x)} (x) = e^{t a n (x) l n (a r c t a n (x))}

= \frac{d}{d x} (e^{t a n (x) l n (a r c t a n (x))})

Wende die Kettenregel an:

e^{t a n (x) l n (a r c t a n (x))} \frac{d}{d x} (tan (x) ln (arctan (x)))

= e^{t a n (x) l n (a r c t a n (x))} \frac{d}{d x} (tan (x) ln (arctan (x)))

\frac{d}{d x} (tan (x) ln (arctan (x))) = sec^{2} (x) ln (arctan (x)) + \frac{tan ( x )}{arctan ( x ) ( x ^{2} + 1 )}

= e^{t a n (x) l n (a r c t a n (x))} (sec^{2} (x) ln (arctan (x)) + \frac{tan ( x )}{arctan ( x ) ( x ^{2} + 1 )})

e^{t a n (x) l n (a r c t a n (x))} = arctan^{t a n (x)} (x)

= arctan^{t a n (x)} (x) (sec^{2} (x) ln (arctan (x)) + \frac{tan ( x )}{arctan ( x ) ( x ^{2} + 1 )})

\int \frac{x}{1 + x ^{3}} d x

\frac{d}{d x} (- 8 x - cos (x))

n = 7 \sum \infty e^{5} - 2 n

\frac{d}{d x} (x^{3} x - 4)
