derivative (ln(t))/t

Lösung

ableitung von

\frac{ln ( t )}{t}

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

Schritte zur Lösung

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

Wende die Quotientenregel an:

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

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

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

\frac{d t}{d t} = 1

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

Vereinfache

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

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

\int \frac{x ^{2} - 256}{x} d x

a re a x = - 3, x = 4, y = e^{2 x}, y = 2 e^{- x}

\frac{d}{d x} (x^{m} a^{2} - x^{2})

\frac{\partial}{\partial x} (x^{2} + 8 x y + 17 y^{2} - 2 y + 1)

\frac{\partial}{\partial x} (sin (2 t))
