als Konstanten

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

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

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = y, g = e^{\frac{y}{z}}

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

\frac{\partial}{\partial y} (y) = 1

\frac{\partial}{\partial y} (e^{\frac{y}{z}}) = \frac{e ^{\frac{y}{z}}}{z}

= x^{2} (1 \cdot e^{\frac{y}{z}} + \frac{e ^{\frac{y}{z}}}{z} y)

Vereinfache

x^{2} (1 \cdot e^{\frac{y}{z}} + \frac{e ^{\frac{y}{z}}}{z} y) : x^{2} (e^{\frac{y}{z}} + \frac{e ^{\frac{y}{z}} y}{z})

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

\frac{\partial}{\partial x} (3 x sin (7 x^{2} y))

\frac{\partial}{\partial x} (x e^{y} - y e^{x})

\int_{0}^{1} \frac{3 ^{3 x} - 1}{3 ^{x}} d x
