(\partial)/(\partial x)(ln(x+4y+9z))

Lösung

\frac{\partial}{\partial x} (ln (x + 4 y + 9 z))

\frac{1}{x + 4 y + 9 z}

Schritte zur Lösung

\frac{\partial}{\partial x} (ln (x + 4 y + 9 z))

Behandle

y, z

als Konstanten

Wende die Kettenregel an:

\frac{1}{x + 4 y + 9 z} \frac{\partial}{\partial x} (x + 4 y + 9 z)

= \frac{1}{x + 4 y + 9 z} \frac{\partial}{\partial x} (x + 4 y + 9 z)

\frac{\partial}{\partial x} (x + 4 y + 9 z) = 1

= \frac{1}{x + 4 y + 9 z} \cdot 1

Vereinfache

= \frac{1}{x + 4 y + 9 z}
