Lösung

\frac{\partial}{\partial x} (2 x^{2} y - 2 x + 4 y^{3})

4 x y - 2

Schritte zur Lösung

\frac{\partial}{\partial x} (2 x^{2} y - 2 x + 4 y^{3})

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

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

= \frac{\partial}{\partial x} (2 x^{2} y) - \frac{\partial}{\partial x} (2 x) + \frac{\partial}{\partial x} (4 y^{3})

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

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

\frac{\partial}{\partial x} (4 y^{3}) = 0

= 4 y x - 2 + 0

Vereinfache

= 4 x y - 2

x \to 0 lim (x^{2 x})
