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

- 2 sin (x)

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

= 2 (- sin (x))

Simplify

= - 2 sin (x)

\int (2 x^{4} - 8 x^{3}) e^{- 3 x} d x

10 y^{^{''}} + 1000 y = 80 cos (8 t)

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

\int x^{3} ln (x^{4}) d x

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