Lösung

\frac{\partial}{\partial x} (x^{3} + 3 x y^{2} - 15 x - 12 y)

3 x^{2} + 3 y^{2} - 15

Schritte zur Lösung

\frac{\partial}{\partial x} (x^{3} + 3 x y^{2} - 15 x - 12 y)

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} (3 x y^{2}) - \frac{\partial}{\partial x} (15 x) - \frac{\partial}{\partial x} (12 y)

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

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

\frac{\partial}{\partial x} (15 x) = 15

\frac{\partial}{\partial x} (12 y) = 0

= 3 x^{2} + 3 y^{2} - 15 - 0

Vereinfache

= 3 x^{2} + 3 y^{2} - 15

\frac{d ^{2} y}{d t ^{2}} - 5 \frac{d y}{d t} - 24 y = 0

x \to 0 - lim (x - 1)

\int_{0}^{1} 3 (x^{2} + 1) e^{- x} d x

x \to 3 + lim (7 x^{2} + 5)

x \to - 1 lim ([x])
