derivative y=(ln(x))/x

Lösung

ableitung von

y = \frac{ln ( x )}{x}

\frac{1 - ln ( x )}{x ^{2}}

Schritte zur Lösung

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

Wende die Quotientenregel an:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( ln ( x ) ) x - \frac{d x}{d x} ln ( x )}{x ^{2}}

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

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

= \frac{\frac{1}{x} x - 1 \cdot ln ( x )}{x ^{2}}

Vereinfache

\frac{\frac{1}{x} x - 1 \cdot ln ( x )}{x ^{2}} : \frac{1 - ln ( x )}{x ^{2}}

= \frac{1 - ln ( x )}{x ^{2}}

\frac{\partial}{\partial x} (A \frac{x}{z})

\frac{d}{d x} (\frac{3 x - 4}{( 5 x + 2 ) ^{3}})

\int_{0}^{3} \frac{1}{36 - x ^{2}} d x

d er i v a t i v e f (x) = (6 x + 2)^{3}

\frac{d}{d x} (\frac{x ^{4}}{4} + \frac{8}{9} x^{3} - x^{2} + 3 x - 8)
