derivative of x(1-cos(x))

Lösung

\frac{d}{d x} (x (1 - cos (x)))

Lösung

1 - cos (x) + x sin (x)

Schritte zur Lösung

\frac{d}{d x} (x (1 - cos (x)))

Wende die Produktregel an:

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

f = x, g = 1 - cos (x)

= \frac{d x}{d x} (1 - cos (x)) + \frac{d}{d x} (1 - cos (x)) x

\frac{d x}{d x} = 1

\frac{d}{d x} (1 - cos (x)) = sin (x)

= 1 \cdot (1 - cos (x)) + sin (x) x

Vereinfache

= 1 - cos (x) + x sin (x)
