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

- sin (2 x) + sin (x)

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

= - sin (2 x) - (- sin (x))

Simplify

= - sin (2 x) + sin (x)

f (r) = 2 π r

f (x) = \frac{e ^{x} - 1 - x}{x}

y^{2} = x^{3}, 1 \leq x \leq 4

f (k) = k^{2}

f (x) = 2 - x
