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

Lösung

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

4 y - x^{2}

Schritte zur Lösung

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

Behandle

x

als Konstante

Wende die Summen-/Differenzregel an:

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

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

\frac{\partial}{\partial y} (x^{2}) = 0

\frac{\partial}{\partial y} (2 y^{2}) = 4 y

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

= 0 + 4 y - x^{2}

Vereinfache

= 4 y - x^{2}
