\frac{d}{d x} (cos (2 x) \cdot 2)

- 4 sin (2 x)

Solution steps

\frac{d}{d x} (cos (2 x) \cdot 2)

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 \frac{d}{d x} (cos (2 x))

Apply the chain rule:

- sin (2 x) \frac{d}{d x} (2 x)

= - sin (2 x) \frac{d}{d x} (2 x)

\frac{d}{d x} (2 x) = 2

= 2 (- sin (2 x) \cdot 2)

Simplify

= - 4 sin (2 x)

d er i v a t i v e y = \frac{x ^{7}}{x ^{5}} x = 0

\int \frac{4 - x}{4 + x} d x

\frac{d}{d x} (ln (\frac{x + 1}{x - 3}))

f (x) = \frac{5}{x ^{3}}

\int 8 u^{\frac{7}{2}} d u
