(\partial)/(\partial x)(x^3-9xy+y^3-2)

Lösung

\frac{\partial}{\partial x} (x^{3} - 9 x y + y^{3} - 2)

3 x^{2} - 9 y

Schritte zur Lösung

\frac{\partial}{\partial x} (x^{3} - 9 x y + y^{3} - 2)

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

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

= \frac{\partial}{\partial x} (x^{3}) - \frac{\partial}{\partial x} (9 x y) + \frac{\partial}{\partial x} (y^{3}) - \frac{\partial}{\partial x} (2)

\frac{\partial}{\partial x} (x^{3}) = 3 x^{2}

\frac{\partial}{\partial x} (9 x y) = 9 y

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

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

= 3 x^{2} - 9 y + 0 - 0
