derivative y=x^2-5x-6

解答

导数

y = x^{2} - 5 x - 6

2 x - 5

求解步骤

\frac{d}{d x} (x^{2} - 5 x - 6)

使用微分加减法定则:

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

= \frac{d}{d x} (x^{2}) - \frac{d}{d x} (5 x) - \frac{d}{d x} (6)

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

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

\frac{d}{d x} (6) = 0

= 2 x - 5 - 0

化简

= 2 x - 5

d er i v a t i v e f (x) = \frac{( x + 9 )}{x ^{2} - 7 x + 1}

d er i v a t i v e g (x) = \frac{7}{x}

\int \frac{4 x ^{5}}{1 - 12 x ^{6}} d x

d er i v a t i v e 12 x^{3} - 18 x^{2}

\int 16 ln (3 x) d x
