integral of-(1300)/(x^2)

解答

\int - \frac{1300}{x ^{2}} d x

\frac{1300}{x} + C

求解步骤

\int - \frac{1300}{x ^{2}} d x

提出常数:

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

= - 1300 \cdot \int \frac{1}{x ^{2}} d x

使用幂法则

= - 1300 (- \frac{1}{x})

化简

- 1300 (- \frac{1}{x}) : \frac{1300}{x}

= \frac{1300}{x}

解答补常数

= \frac{1300}{x} + C

\frac{d}{d x} (\frac{3 x}{x})
