$$$\frac{1}{\sqrt{y}}$$$의 적분

$$$\int \frac{1}{\sqrt{y}}\, dy$$$을(를) 구하시오.

멱법칙($$$\int y^{n}\, dy = \frac{y^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$)을 $$$n=- \frac{1}{2}$$$에 적용합니다:

$${\color{red}{\int{\frac{1}{\sqrt{y}} d y}}}={\color{red}{\int{y^{- \frac{1}{2}} d y}}}={\color{red}{\frac{y^{- \frac{1}{2} + 1}}{- \frac{1}{2} + 1}}}={\color{red}{\left(2 y^{\frac{1}{2}}\right)}}={\color{red}{\left(2 \sqrt{y}\right)}}$$

따라서,

$$\int{\frac{1}{\sqrt{y}} d y} = 2 \sqrt{y}$$

적분 상수를 추가하세요:

$$\int{\frac{1}{\sqrt{y}} d y} = 2 \sqrt{y}+C$$

$$$\int \frac{1}{\sqrt{y}}\, dy = 2 \sqrt{y} + C$$$A
