Wende die Produktregel an:

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

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

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

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

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

= 1 \cdot e^{\frac{x}{y}} + \frac{e ^{\frac{x}{y}}}{y} x

Vereinfache

1 \cdot e^{\frac{x}{y}} + \frac{e ^{\frac{x}{y}}}{y} x : e^{\frac{x}{y}} + \frac{e ^{\frac{x}{y}} x}{y}

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