integral of (1+x)^{-1/2}

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

2 (1 + x)^{\frac{1}{2}} + C

Solution steps

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

Apply u-substitution

= \int \frac{1}{u ^{\frac{1}{2}}} d u

Apply the Power Rule

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

Substitute back

u = 1 + x

= 2 (1 + x)^{\frac{1}{2}}

Add a constant to the solution

= 2 (1 + x)^{\frac{1}{2}} + C
