integral of (-7+9/(sqrt(p)))

解答

\int (- 7 + \frac{9}{p}) d p

- 7 p + 18 p + C

求解步骤

\int - 7 + \frac{9}{p} d p

使用积分加法定则:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - \int 7 d p + \int \frac{9}{p} d p

\int 7 d p = 7 p

\int \frac{9}{p} d p = 18 p

= - 7 p + 18 p

解答补常数

= - 7 p + 18 p + C

\int (2 x - 6)^{2} d x

\int (x^{\frac{1}{2}} + x^{- \frac{1}{2}}) d x

\int (1 + x^{2}) e^{3 x} d x

\int x^{2} e^{1 - x^{3}} d x

\int (4 x^{3} + 3 3 x^{2}) d x
