d/(da)(3sin^2(a)-2cos^2(a))

解

\frac{d}{d a} (3 sin^{2} (a) - 2 cos^{2} (a))

解

5 sin (2 a)

解答ステップ

\frac{d}{d a} (3 sin^{2} (a) - 2 cos^{2} (a))

和/差の法則を適用:

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

= \frac{d}{d a} (3 sin^{2} (a)) - \frac{d}{d a} (2 cos^{2} (a))

\frac{d}{d a} (3 sin^{2} (a)) = 3 sin (2 a)

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

= 3 sin (2 a) - (- 2 sin (2 a))

簡素化

= 5 sin (2 a)
