Lösung

\frac{\partial}{\partial y} (3 y^{2} x + x^{3} + y x^{2})

x^{2} + 6 y x

Schritte zur Lösung

\frac{\partial}{\partial y} (3 y^{2} x + x^{3} + y x^{2})

Behandle

x

als Konstante

Wende die Summen-/Differenzregel an:

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

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

\frac{\partial}{\partial y} (3 y^{2} x) = 6 x y

\frac{\partial}{\partial y} (x^{3}) = 0

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

= 6 x y + 0 + x^{2}

Vereinfache

= x^{2} + 6 y x
