integral from 3 to 3.6 of 1/x

解答

\int_{3}^{3.6} \frac{1}{x} d x

0.18232 \dots

求解步骤

\int_{3}^{3.6} \frac{1}{x} d x

使用积分常见定则:

\int \frac{1}{x} d x = ln (∣ x ∣)

= [ln ∣ x ∣]_{3}^{3.6}

带入上下限计算后得:

0.18232 \dots

= 0.18232 \dots

\int_{1}^{8} x^{2} x^{3} + 1 d x

\int_{1}^{3} (z - 2)^{3} d z

\int_{1}^{x + c} 1 d x

\int_{- 3}^{3} 3 - ∣ x ∣ d x

\int_{0}^{4} 8 - 2 x d x
