(\partial)/(\partial x)(1/(ln(2/x)))

\frac{\partial}{\partial x} (\frac{1}{ln ( \frac{2}{x} )})

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

Solution steps

\frac{\partial}{\partial x} (\frac{1}{ln ( \frac{2}{x} )})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

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

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

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

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

Simplify

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

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