Schritte zur Lösung

\frac{d}{d x} ((x + cos (x))^{c o t (x)})

Wende Exponentenregel an:

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

(x + cos (x))^{c o t (x)} = e^{c o t (x) l n (x + c o s (x))}

= \frac{d}{d x} (e^{c o t (x) l n (x + c o s (x))})

Wende die Kettenregel an:

e^{c o t (x) l n (x + c o s (x))} \frac{d}{d x} (cot (x) ln (x + cos (x)))

= e^{c o t (x) l n (x + c o s (x))} \frac{d}{d x} (cot (x) ln (x + cos (x)))

\frac{d}{d x} (cot (x) ln (x + cos (x))) = \frac{- cos ( x ) + cot ( x ) - csc ^{2} ( x ) ln ( x + cos ( x ) ) ( x + cos ( x ) )}{x + cos ( x )}

= e^{c o t (x) l n (x + c o s (x))} \frac{- cos ( x ) + cot ( x ) - csc ^{2} ( x ) ln ( x + cos ( x ) ) ( x + cos ( x ) )}{x + cos ( x )}

= (- cos (x) + cot (x) - csc^{2} (x) ln (x + cos (x)) (x + cos (x))) (x + cos (x))^{c o t (x) - 1}
