derivative of cos(a^3+x^3)

解

\frac{d}{d x} (cos (a^{3} + x^{3}))

解

- sin (a^{3} + x^{3}) \cdot 3 x^{2}

解答ステップ

\frac{d}{d x} (cos (a^{3} + x^{3}))

連鎖法則を適用:

- sin (a^{3} + x^{3}) \frac{d}{d x} (a^{3} + x^{3})

= - sin (a^{3} + x^{3}) \frac{d}{d x} (a^{3} + x^{3})

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

= - sin (a^{3} + x^{3}) \cdot 3 x^{2}
