derivative cos(4x^2)

解答

导数

cos (4 x^{2})

- sin (4 x^{2}) \cdot 8 x

求解步骤

\frac{d}{d x} (cos (4 x^{2}))

使用连锁律:

- sin (4 x^{2}) \frac{d}{d x} (4 x^{2})

= - sin (4 x^{2}) \frac{d}{d x} (4 x^{2})

\frac{d}{d x} (4 x^{2}) = 8 x

= - sin (4 x^{2}) \cdot 8 x

\int \frac{( x + 9 )}{x} d x

\int \frac{1}{3 - 3 x} d x

x y y^{^{'}} = 1 + y^{2}

d er i v a t i v e f (x) = 0.882 x^{0.842}

\frac{d}{d x} (\frac{4 x + 1 1 + x}{x ^{2} - 1})
