(\partial)/(\partial z)(ln(x+2y+3z))

Lösung

\frac{\partial}{\partial z} (ln (x + 2 y + 3 z))

\frac{3}{x + 2 y + 3 z}

Schritte zur Lösung

\frac{\partial}{\partial z} (ln (x + 2 y + 3 z))

Behandle

x, y

als Konstanten

Wende die Kettenregel an:

\frac{1}{x + 2 y + 3 z} \frac{\partial}{\partial z} (x + 2 y + 3 z)

= \frac{1}{x + 2 y + 3 z} \frac{\partial}{\partial z} (x + 2 y + 3 z)

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

= \frac{1}{x + 2 y + 3 z} \cdot 3

Vereinfache

\frac{1}{x + 2 y + 3 z} \cdot 3 : \frac{3}{x + 2 y + 3 z}

= \frac{3}{x + 2 y + 3 z}
