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

4 sin (x)

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (1) = 0

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

= 0 - (- 4 sin (x))

Simplify

= 4 sin (x)

\int_{- 2}^{2} \frac{1}{x ^{2} - 9} d x

\int tan^{4} (x se) c^{2} x d x

\int \frac{( 3 + ln ( 2 x ) ) ^{3}}{x} d x

\frac{d v}{d t} = 9.8 - v

f (x) = x e^{2 x^{2} - 4 x}
