derivative of

f (x) = ln (7 x)

\frac{1}{x}

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

\frac{1}{7 x} \cdot 7 : \frac{1}{x}

= \frac{1}{x}

\frac{\partial}{\partial z} (\frac{y}{1 + x ^{2} y ^{2}})

x^{9} sin (x)

(x - 5) (5 x + 3)

x^{- 4}

\int_{2}^{4} \frac{6}{2 x - 9} d x
