derivative of 5x-e

解答

\frac{d}{d x} (5 x - e)

5

求解步骤

\frac{d}{d x} (5 x - e)

使用微分加减法定则:

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

= \frac{d}{d x} (5 x) - \frac{d e}{d x}

\frac{d}{d x} (5 x) = 5

\frac{d e}{d x} = 0

= 5 - 0

化简

= 5

\frac{\partial}{\partial x} (\frac{6 x - 7 y}{y ^{2} + x ^{2}})

x y^{^{'}} = y + x^{2} sin (x), y (\frac{π}{6}) = 0

\frac{d}{d x} ((\frac{x ^{2} + 2}{x ^{3} - 1})^{3})

in v erse l a pl a ce \frac{1}{s ^{3} ( s ^{2} + 1 )}

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