\frac{\partial}{\partial x} (x^{3} z + z^{3} x - 2 yz)

z^{3} + 3 x^{2} z

Schritte zur Lösung

\frac{\partial}{\partial x} (x^{3} z + z^{3} x - 2 yz)

Behandle

z, y

als Konstanten

Wende die Summen-/Differenzregel an:

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

= \frac{\partial}{\partial x} (x^{3} z) + \frac{\partial}{\partial x} (z^{3} x) - \frac{\partial}{\partial x} (2 yz)

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

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

\frac{\partial}{\partial x} (2 yz) = 0

= 3 z x^{2} + z^{3} - 0

Vereinfache

= z^{3} + 3 x^{2} z
