derivative of x^{10}e^{x+10}

解答

\frac{d}{d x} (x^{10} e^{x + 10})

10 x^{9} e^{x + 10} + e^{x + 10} x^{10}

求解步骤

\frac{d}{d x} (x^{10} e^{x + 10})

使用微分乘法定则:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{10}, g = e^{x + 10}

= \frac{d}{d x} (x^{10}) e^{x + 10} + \frac{d}{d x} (e^{x + 10}) x^{10}

\frac{d}{d x} (x^{10}) = 10 x^{9}

\frac{d}{d x} (e^{x + 10}) = e^{x + 10}

= 10 x^{9} e^{x + 10} + e^{x + 10} x^{10}

\int_{0}^{1} \frac{5}{x ( 1 + x )} d x

\frac{d y}{d t} = k (80 - y) (50 - y)

x \to 4 lim (1 - 2 x)

\int_{0}^{1} t e^{2 t} d t

t an g e n t tan (x), at x = - \frac{π}{3}
