derivative of 5xln(3x)

Lösung

\frac{d}{d x} (5 x ln (3 x))

5 (ln (3 x) + 1)

Schritte zur Lösung

\frac{d}{d x} (5 x ln (3 x))

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= 5 \frac{d}{d x} (x ln (3 x))

Wende die Produktregel an:

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

f = x, g = ln (3 x)

= 5 (\frac{d x}{d x} ln (3 x) + \frac{d}{d x} (ln (3 x)) x)

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

\frac{d}{d x} (ln (3 x)) = \frac{1}{x}

= 5 (1 \cdot ln (3 x) + \frac{1}{x} x)

Vereinfache

5 (1 \cdot ln (3 x) + \frac{1}{x} x) : 5 (ln (3 x) + 1)

= 5 (ln (3 x) + 1)

\frac{\partial}{\partial x} (x cos (y))

\int x^{2} cos (x^{3} + 10) d x

t a y l or ln (1 - x)

\int \frac{y ^{5}}{1 - y ^{4}} d y
