derivative of

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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

\int sec^{2} (x) - 1 d x

\int \frac{1}{4 x - x ^{2}} d x

\frac{d}{d x} (arctan (2 x + 1))

x \to \infty lim (e^{1})

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