Behandle

y

als Konstante

Wende die Kettenregel an:

\frac{1}{2 4 - x ^{2} - 2 y} \frac{\partial}{\partial x} (4 - x^{2} - 2 y)

= \frac{1}{2 4 - x ^{2} - 2 y} \frac{\partial}{\partial x} (4 - x^{2} - 2 y)

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

= \frac{1}{2 4 - x ^{2} - 2 y} (- 2 x)

Vereinfache

\frac{1}{2 4 - x ^{2} - 2 y} (- 2 x) : - \frac{x}{4 - x ^{2} - 2 y}

= - \frac{x}{4 - x ^{2} - 2 y}
