integral of (9-x)^{1/2}

\int (9 - x)^{\frac{1}{2}} d x

- \frac{2}{3} (9 - x)^{\frac{3}{2}} + C

Solution steps

\int (9 - x)^{\frac{1}{2}} d x

Apply u-substitution

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

Take the constant out:

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

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

Apply the Power Rule

= - \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 9 - x

= - \frac{2}{3} (9 - x)^{\frac{3}{2}}

Add a constant to the solution

= - \frac{2}{3} (9 - x)^{\frac{3}{2}} + C
