derivative of

f (x) = ln (3 x)

\frac{1}{x}

Solution steps

\frac{d}{d x} (ln (3 x))

Apply the chain rule:

\frac{1}{3 x} \frac{d}{d x} (3 x)

= \frac{1}{3 x} \frac{d}{d x} (3 x)

\frac{d}{d x} (3 x) = 3

= \frac{1}{3 x} \cdot 3

Simplify

\frac{1}{3 x} \cdot 3 : \frac{1}{x}

= \frac{1}{x}

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

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

\int 9 x (9 - x^{- 4}) d x

\frac{d}{d x} (u (x) (x)^{3} + 4)

x \to 3 - lim (\frac{x - 3}{x ^{2} - 9})
