derivative of

ln (1 - 7 x)

- \frac{7}{1 - 7 x}

Solution steps

\frac{d}{d x} (ln (1 - 7 x))

Apply the chain rule:

\frac{1}{1 - 7 x} \frac{d}{d x} (1 - 7 x)

= \frac{1}{1 - 7 x} \frac{d}{d x} (1 - 7 x)

\frac{d}{d x} (1 - 7 x) = - 7

= \frac{1}{1 - 7 x} (- 7)

Simplify

\frac{1}{1 - 7 x} (- 7) : - \frac{7}{1 - 7 x}

= - \frac{7}{1 - 7 x}
