(\partial)/(\partial x)(sin(x)+xcos(x))

Lösung

\frac{\partial}{\partial x} (sin (x) + x cos (x))

2 cos (x) - x sin (x)

Schritte zur Lösung

\frac{\partial}{\partial x} (sin (x) + x cos (x))

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial x} (sin (x)) + \frac{\partial}{\partial x} (x cos (x))

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

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

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