integral from 0 to a of ysqrt(a^2-y^2)

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

\frac{( a ^{2} ) ^{\frac{3}{2}}}{3}

Solution steps

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

Apply u-substitution

= \int_{a^{2}}^{0} - \frac{u}{2} d u

Take the constant out:

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

= - \frac{1}{2} \cdot \int_{a^{2}}^{0} u d u

Apply the Power Rule

= - \frac{1}{2} [\frac{2}{3} u^{\frac{3}{2}}]_{a^{2}}^{0}

Compute the boundaries:

- \frac{2}{3} (a^{2})^{\frac{3}{2}}

= - \frac{1}{2} (- \frac{2}{3} (a^{2})^{\frac{3}{2}})

Simplify

= \frac{( a ^{2} ) ^{\frac{3}{2}}}{3}
