\frac{\partial}{\partial x} (ln (\frac{x}{4} + \frac{y}{12}))

\frac{3}{3 x + y}

Schritte zur Lösung

\frac{\partial}{\partial x} (ln (\frac{x}{4} + \frac{y}{12}))

Behandle

y

als Konstante

Wende die Kettenregel an:

\frac{1}{\frac{x}{4} + \frac{y}{12}} \frac{\partial}{\partial x} (\frac{x}{4} + \frac{y}{12})

= \frac{1}{\frac{x}{4} + \frac{y}{12}} \frac{\partial}{\partial x} (\frac{x}{4} + \frac{y}{12})

\frac{\partial}{\partial x} (\frac{x}{4} + \frac{y}{12}) = \frac{1}{4}

= \frac{1}{\frac{x}{4} + \frac{y}{12}} \cdot \frac{1}{4}

Vereinfache

\frac{1}{\frac{x}{4} + \frac{y}{12}} \cdot \frac{1}{4} : \frac{3}{3 x + y}

= \frac{3}{3 x + y}
