derivative of

cos^{2} (3 x - 1)

- 6 cos (3 x - 1) sin (3 x - 1)

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

= - 6 cos (3 x - 1) sin (3 x - 1)

y = x - 3, y = - x - 1, x = 1, x = 3

x^{\frac{9}{6}}, 8

(9 - x^{3})^{5}

\int \frac{4}{5} - \frac{9}{x} d x

f (2) = 2 x^{3} - 1
