integral from y^2 to y of sqrt(y/x)

\int_{y^{2}}^{y} \frac{y}{x} d x

- y (- 2 + 2 y)

Solution steps

\int_{y^{2}}^{y} \frac{y}{x} d x

Apply u-substitution

= \int_{\frac{1}{y}}^{1} - \frac{y}{u ^{\frac{3}{2}}} d u

Take the constant out:

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

= - y \cdot \int_{\frac{1}{y}}^{1} \frac{1}{u ^{\frac{3}{2}}} d u

Apply the Power Rule

= - y [- \frac{2}{u}]_{\frac{1}{y}}^{1}

Compute the boundaries:

- 2 + 2 y

= - y (- 2 + 2 y)
