als Konstante

Entferne die Konstante:

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

= 250 \frac{\partial}{\partial x} (x^{2} + y^{2})

Wende die Kettenregel an:

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

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

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

= 250 \cdot \frac{1}{2 x ^{2} + y ^{2}} \cdot 2 x

Vereinfache

250 \cdot \frac{1}{2 x ^{2} + y ^{2}} \cdot 2 x : \frac{250 x}{x ^{2} + y ^{2}}

= \frac{250 x}{x ^{2} + y ^{2}}
