derivative of

\frac{d}{d 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

f (x) = arctan (x)

\frac{d}{d x} (e^{- 2 x})

\frac{d}{d x} (x y)

x, y = 0, x = 2, y = x

csc (x) cot (x)
