derivative f(x)=5x-1

解答

导数

f (x) = 5 x - 1

5

求解步骤

\frac{d}{d x} (5 x - 1)

使用微分加减法定则:

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

= \frac{d}{d x} (5 x) - \frac{d}{d x} (1)

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

\frac{d}{d x} (1) = 0

= 5 - 0

化简

= 5

x^{4} y^{^{'}} + 3 x^{3} y = x^{2} e^{x}

\frac{d}{d x} (\frac{3 x - 9}{2 x + 4})

\int \frac{1}{16 x ^{2} + 25} d x

\int 15 - 2 x - x^{2} d x

\frac{d y}{d t} + k (340 - y) = 0
