derivative cos(x)-4tan(x)

解

導関数

cos (x) - 4 tan (x)

解

- sin (x) - 4 sec^{2} (x)

解答ステップ

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

和/差の法則を適用:

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

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

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

\frac{d}{d x} (4 tan (x)) = 4 sec^{2} (x)

= - sin (x) - 4 sec^{2} (x)
