(\partial)/(\partial y)((x)(x^2y-xy^2))

Lösung

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

x (x^{2} - 2 x y)

Schritte zur Lösung

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

Behandle

x

als Konstante

Entferne die Konstante:

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

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

Wende die Summen-/Differenzregel an:

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

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

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

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

= x (x^{2} - 2 x y)
