derivative of x*ln(x+1)

Lösung

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

Lösung

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

Schritte zur Lösung

\frac{d}{d x} (x ln (x + 1))

Wende die Produktregel an:

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

f = x, g = ln (x + 1)

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

\frac{d x}{d x} = 1

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

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

Vereinfache

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

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