\frac{d}{d x} (cos (1 - 4 x))

4 sin (1 - 4 x)

Solution steps

\frac{d}{d x} (cos (1 - 4 x))

Apply the chain rule:

- sin (1 - 4 x) \frac{d}{d x} (1 - 4 x)

= - sin (1 - 4 x) \frac{d}{d x} (1 - 4 x)

\frac{d}{d x} (1 - 4 x) = - 4

= - sin (1 - 4 x) (- 4)

Simplify

= 4 sin (1 - 4 x)

f (x) = \frac{3 - ( \frac{1}{x ^{2}} )}{x + 4}

\int e^{- s t} cos (t) d t

t y^{^{'}} = 2

\frac{d}{d x} (sec^{2} (x))

\frac{d}{d x} (\frac{sin ( x )}{8 x e ^{x}})
