(\partial)/(\partial x)(x*ln(x))

Lösung

\frac{\partial}{\partial x} (x \cdot ln (x))

ln (x) + 1

Schritte zur Lösung

\frac{\partial}{\partial x} (x ln (x))

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = ln (x)

= \frac{\partial}{\partial x} (x) ln (x) + \frac{\partial}{\partial x} (ln (x)) x

\frac{\partial}{\partial x} (x) = 1

\frac{\partial}{\partial x} (ln (x)) = \frac{1}{x}

= 1 \cdot ln (x) + \frac{1}{x} x

Vereinfache

1 \cdot ln (x) + \frac{1}{x} x : ln (x) + 1

= ln (x) + 1
