derivative of xe^{sin(x})

Lösung

\frac{d}{d x} (x e^{s i n (x)})

Lösung

e^{s i n (x)} + e^{s i n (x)} x cos (x)

Schritte zur Lösung

\frac{d}{d x} (x e^{s i n (x)})

Wende die Produktregel an:

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

f = x, g = e^{s i n (x)}

= \frac{d x}{d x} e^{s i n (x)} + \frac{d}{d x} (e^{s i n (x)}) x

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

\frac{d}{d x} (e^{s i n (x)}) = e^{s i n (x)} cos (x)

= 1 \cdot e^{s i n (x)} + e^{s i n (x)} cos (x) x

Vereinfache

= e^{s i n (x)} + e^{s i n (x)} x cos (x)
