derivative of

ln (9 - 7 x)

- \frac{7}{9 - 7 x}

Solution steps

\frac{d}{d x} (ln (9 - 7 x))

Apply the chain rule:

\frac{1}{9 - 7 x} \frac{d}{d x} (9 - 7 x)

= \frac{1}{9 - 7 x} \frac{d}{d x} (9 - 7 x)

\frac{d}{d x} (9 - 7 x) = - 7

= \frac{1}{9 - 7 x} (- 7)

Simplify

\frac{1}{9 - 7 x} (- 7) : - \frac{7}{9 - 7 x}

= - \frac{7}{9 - 7 x}

\int \frac{3 x ^{2} + 2 x + 1}{x} d x

\frac{d}{d x} (\frac{sin ( 2 x )}{x})

\int sin^{2} (4 θ) d θ
