als Konstante

Wende die Kettenregel an:

\frac{1}{2 \frac{x}{x + y}} \frac{\partial}{\partial x} (\frac{x}{x + y})

= \frac{1}{2 \frac{x}{x + y}} \frac{\partial}{\partial x} (\frac{x}{x + y})

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

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

Vereinfache

\frac{1}{2 \frac{x}{x + y}} \cdot \frac{y}{( x + y ) ^{2}} : \frac{y}{2 x ( x + y ) ^{\frac{3}{2}}}

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