derivative y=2-x^2

解答

导数

y = 2 - x^{2}

- 2 x

求解步骤

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

使用微分加减法定则:

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

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

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

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

= 0 - 2 x

化简

= - 2 x

\int_{- 2 π}^{π} π sin^{2} (x) d x

\frac{d y}{d x} = \frac{x ^{2} - x + 2}{x} + y

\int 5 sin (5 x - 3) d x

d er i v a t i v e 4 x - 4 e^{x}

a re a sin (x), 5 - x^{2}, [- 2.384677, 2.0252116]
