(\partial)/(\partial x)(x^3e^ysin(x-y))

Lösung

\frac{\partial}{\partial x} (x^{3} e^{y} sin (x - y))

e^{y} (3 x^{2} sin (x - y) + cos (x - y) x^{3})

Schritte zur Lösung

\frac{\partial}{\partial x} (x^{3} e^{y} sin (x - y))

Behandle

y

als Konstante

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= e^{y} \frac{\partial}{\partial x} (x^{3} sin (x - y))

Wende die Produktregel an:

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

f = x^{3}, g = sin (x - y)

= e^{y} (\frac{\partial}{\partial x} (x^{3}) sin (x - y) + \frac{\partial}{\partial x} (sin (x - y)) x^{3})

\frac{\partial}{\partial x} (x^{3}) = 3 x^{2}

\frac{\partial}{\partial x} (sin (x - y)) = cos (x - y)

= e^{y} (3 x^{2} sin (x - y) + cos (x - y) x^{3})
