integral of 1/(sqrt(w))

解答

\int \frac{1}{w} d w

2 w + C

求解步骤

\int \frac{1}{w} d w

使用幂法则

= 2 w^{\frac{1}{2}}

使用根式运算法则:

a^{\frac{1}{n}} = n a

= 2 w

解答补常数

= 2 w + C

\int \frac{1}{u ^{2} - a ^{2}} d u

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

\int_{- 3}^{3} - 9 - x^{2} d x

\int (x - 3)^{- 1} d x

\int \frac{1 + x ^{8}}{x ^{13}} d x
