derivative of 2x-3x^2

解答

\frac{d}{d x} (2 x - 3 x^{2})

2 - 6 x

求解步骤

\frac{d}{d x} (2 x - 3 x^{2})

使用微分加减法定则:

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

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

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

\frac{d}{d x} (3 x^{2}) = 6 x

= 2 - 6 x

\frac{\partial}{\partial y} (- 2 x y - y^{4})

x \to 0 lim (\frac{x - sin ( x )}{e ^{x} - 1 - x - \frac{x ^{2}}{2}})

\int \frac{y ^{2} - 100}{y} d y
