Lösung

\frac{d}{d x} (ln (cos (e^{x^{2} - s e c (x)})))

- e^{x^{2} - s e c (x)} tan (e^{x^{2} - s e c (x)}) (2 x - sec (x) tan (x))

Schritte zur Lösung

\frac{d}{d x} (ln (cos (e^{x^{2} - s e c (x)})))

Wende die Kettenregel an:

\frac{1}{cos ( e ^{x^{2} - s e c (x)} )} \frac{d}{d x} (cos (e^{x^{2} - s e c (x)}))

= \frac{1}{cos ( e ^{x^{2} - s e c (x)} )} \frac{d}{d x} (cos (e^{x^{2} - s e c (x)}))

\frac{d}{d x} (cos (e^{x^{2} - s e c (x)})) = - sin (e^{x^{2} - s e c (x)}) e^{x^{2} - s e c (x)} (2 x - sec (x) tan (x))

= \frac{1}{cos ( e ^{x^{2} - s e c (x)} )} (- sin (e^{x^{2} - s e c (x)}) e^{x^{2} - s e c (x)} (2 x - sec (x) tan (x)))

= - e^{x^{2} - s e c (x)} tan (e^{x^{2} - s e c (x)}) (2 x - sec (x) tan (x))
