integral from 0 to 2a of sqrt(2ay)

\int_{0}^{2 a} 2 a y d y

\frac{8 a a ^{\frac{3}{2}}}{3}

Solution steps

\int_{0}^{2 a} 2 a y d y

Apply radical rule:

assuming

a \geq 0, b \geq 0

= \int_{0}^{2 a} 2 a y d y

Take the constant out:

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

= 2 \cdot \int_{0}^{2 a} a y d y

a y = a y

= 2 \cdot \int_{0}^{2 a} a y d y

Take the constant out:

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

= 2 a \cdot \int_{0}^{2 a} y d y

Apply the Power Rule

= 2 a [\frac{2}{3} y^{\frac{3}{2}}]_{0}^{2 a}

Compute the boundaries:

\frac{4 2}{3} a^{\frac{3}{2}}

= 2 a \frac{4 2}{3} a^{\frac{3}{2}}

Simplify

= \frac{8 a a ^{\frac{3}{2}}}{3}
