derivative of

f (x) = cos^{3} (3 x - 1)

- 9 cos^{2} (3 x - 1) sin (3 x - 1)

Solution steps

\frac{d}{d x} (cos^{3} (3 x - 1))

Apply the chain rule:

3 (cos (3 x - 1))^{2} \frac{d}{d x} (cos (3 x - 1))

= 3 (cos (3 x - 1))^{2} \frac{d}{d x} (cos (3 x - 1))

\frac{d}{d x} (cos (3 x - 1)) = - sin (3 x - 1) \cdot 3

= 3 (cos (3 x - 1))^{2} (- sin (3 x - 1) \cdot 3)

Simplify

= - 9 cos^{2} (3 x - 1) sin (3 x - 1)

\frac{900}{x}

2 x^{- 1}

tan^{4} (3 x^{2} + 4)

\frac{d}{d x} (\frac{( 3 x - y )}{( x + 2 y )})

9 ln (x + 8)
