derivative y=x^5cos(x)

Lösung

ableitung von

y = x^{5} cos (x)

Lösung

5 x^{4} cos (x) - x^{5} sin (x)

Schritte zur Lösung

\frac{d}{d x} (x^{5} cos (x))

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{5}, g = cos (x)

= \frac{d}{d x} (x^{5}) cos (x) + \frac{d}{d x} (cos (x)) x^{5}

\frac{d}{d x} (x^{5}) = 5 x^{4}

\frac{d}{d x} (cos (x)) = - sin (x)

= 5 x^{4} cos (x) + (- sin (x)) x^{5}

Vereinfache

= 5 x^{4} cos (x) - x^{5} sin (x)
