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

Lösung

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

- 2 y - 4 x

Schritte zur Lösung

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

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

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

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

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

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

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

= 0 - 2 y - 4 x
