(\partial)/(\partial z)(xyz+xy^5+yz^5+zx^5)

Lösung

\frac{\partial}{\partial z} (x yz + x y^{5} + y z^{5} + z x^{5})

x^{5} + x y + 5 y z^{4}

Schritte zur Lösung

\frac{\partial}{\partial z} (x yz + x y^{5} + y z^{5} + z x^{5})

Behandle

x, y

als Konstanten

Wende die Summen-/Differenzregel an:

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

= \frac{\partial}{\partial z} (x yz) + \frac{\partial}{\partial z} (x y^{5}) + \frac{\partial}{\partial z} (y z^{5}) + \frac{\partial}{\partial z} (z x^{5})

\frac{\partial}{\partial z} (x yz) = x y

\frac{\partial}{\partial z} (x y^{5}) = 0

\frac{\partial}{\partial z} (y z^{5}) = 5 y z^{4}

\frac{\partial}{\partial z} (z x^{5}) = x^{5}

= x y + 0 + 5 y z^{4} + x^{5}

Vereinfache

= x^{5} + x y + 5 y z^{4}
