(\partial)/(\partial x)(-5x^2-5y^2+xy)

Lösung

\frac{\partial}{\partial x} (- 5 x^{2} - 5 y^{2} + x y)

y - 10 x

Schritte zur Lösung

\frac{\partial}{\partial x} (- 5 x^{2} - 5 y^{2} + x y)

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

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

= - \frac{\partial}{\partial x} (5 x^{2}) - \frac{\partial}{\partial x} (5 y^{2}) + \frac{\partial}{\partial x} (x y)

\frac{\partial}{\partial x} (5 x^{2}) = 10 x

\frac{\partial}{\partial x} (5 y^{2}) = 0

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

= - 10 x - 0 + y

Vereinfache

= y - 10 x
