als Konstante

Wende die Summen-/Differenzregel an:

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

= \frac{\partial}{\partial x} (5 x^{4}) + \frac{\partial}{\partial x} (x^{3} y) + \frac{\partial}{\partial x} (x y) + \frac{\partial}{\partial x} (y^{4})

\frac{\partial}{\partial x} (5 x^{4}) = 20 x^{3}

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

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

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

= 20 x^{3} + 3 y x^{2} + y + 0

Vereinfache

= 20 x^{3} + 3 x^{2} y + y

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

\frac{d y}{d x} + e^{x} y^{2} = x^{2} y^{2}

\frac{d}{d x} (4 sec (7 x))

\frac{d}{d x} (22 - x)
