derivative x^{2.4}+e^{2.4}

解答

导数

x^{2.4} + e^{2.4}

2.4 x^{1.4}

求解步骤

\frac{d}{d x} (x^{2.4} + e^{2.4})

化简

x^{2.4} + e^{2.4} : x^{2.4} + 11.02317 \dots

= \frac{d}{d x} (x^{2.4} + 11.02317 \dots)

使用微分加减法定则:

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

= \frac{d}{d x} (x^{2.4}) + \frac{d}{d x} (11.02317 \dots)

\frac{d}{d x} (x^{2.4}) = 2.4 x^{1.4}

\frac{d}{d x} (11.02317 \dots) = 0

= 2.4 x^{1.4} + 0

化简

= 2.4 x^{1.4}

x \to 4 - lim (\frac{15}{x - 4})

a re a y = 20 + x - x^{2}, x^{2} - 5 x

\int (3 x^{5} - 2 x^{3}) d x

d er i v a t i v e cos (tan (x))

d er i v a t i v e y = - 2 x^{2}
