derivative of 2ln(xy)

Lösung

\frac{d}{d x} (2 ln (x y))

\frac{2 ( y + x \frac{d y}{d x} )}{x y}

Schritte zur Lösung

\frac{d}{d x} (2 ln (x y))

Entferne die Konstante:

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

= 2 \frac{d}{d x} (ln (x y))

Wende die Kettenregel an:

\frac{1}{x y} \frac{d}{d x} (x y)

= \frac{1}{x y} \frac{d}{d x} (x y)

\frac{d}{d x} (x y) = y + x \frac{d y}{d x}

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

Vereinfache

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

= \frac{2 ( y + x \frac{d y}{d x} )}{x y}
