derivative of cos(x-1/2)

解

\frac{d}{d x} (cos (x) - \frac{1}{2})

解

- sin (x)

解答ステップ

\frac{d}{d x} (cos (x) - \frac{1}{2})

和/差の法則を適用:

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

= \frac{d}{d x} (cos (x)) - \frac{d}{d x} (\frac{1}{2})

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

\frac{d}{d x} (\frac{1}{2}) = 0

= - sin (x) - 0

簡素化

= - sin (x)
