derivative of

f (x) = cos (3 x)

- sin (3 x) \cdot 3

Solution steps

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

Apply the chain rule:

- sin (3 x) \frac{d}{d x} (3 x)

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

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

= - sin (3 x) \cdot 3

\frac{d}{d x} (3 + 2 sin (x))

\int_{0}^{x} a^{2} - x^{2} d x

\frac{d}{d x} (y^{2} - x^{3} + 8)

ln (x + 1)

X^{^{'}}
