(\partial)/(\partial x)(2+xln(xy-9))

Lösung

\frac{\partial}{\partial x} (2 + x ln (x y - 9))

\frac{x y}{x y - 9} + ln (x y - 9)

Schritte zur Lösung

\frac{\partial}{\partial x} (2 + x ln (x y - 9))

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial x} (2) + \frac{\partial}{\partial x} (x ln (x y - 9))

\frac{\partial}{\partial x} (2) = 0

\frac{\partial}{\partial x} (x ln (x y - 9)) = ln (y x - 9) + \frac{y x}{y x - 9}

= 0 + ln (y x - 9) + \frac{y x}{y x - 9}

Vereinfache

= \frac{x y}{x y - 9} + ln (x y - 9)
