integral from 1200 to 1210 of 0.1x

解答

\int_{1200}^{1210} 0.1 x d x

1205

求解步骤

\int_{1200}^{1210} 0.1 x d x

提出常数:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 0.1 \cdot \int_{1200}^{1210} x d x

使用幂法则

= 0.1 [\frac{x ^{2}}{2}]_{1200}^{1210}

化简

= 0.1 [0.5 x^{2}]_{1200}^{1210}

带入上下限计算后得:

12050

= 0.1 \cdot 12050

化简

= 1205

x \to 0 lim (x^{3} \cdot ln (x))

\frac{\partial}{\partial z} (3)

d er i v a t i v e sin (x^{2})

d er i v a t i v e f (s) = 8^{2 s - 1}

x \to \infty lim (- \frac{5}{x})
