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

Lösung

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

2 x + 2 y

Schritte zur Lösung

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

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

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

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

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

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

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

= 2 x + 0 + 2 y
