integral from 1 to 5 of sqrt(2x-1)

\int_{1}^{5} 2 x - 1 d x

\frac{26}{3}

Decimal

8.66666 \dots

Solution steps

\int_{1}^{5} 2 x - 1 d x

Apply u-substitution

= \int_{1}^{9} \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_{1}^{9} u d u

Apply the Power Rule

= \frac{1}{2} [\frac{2}{3} u^{\frac{3}{2}}]_{1}^{9}

Compute the boundaries:

\frac{52}{3}

= \frac{1}{2} \cdot \frac{52}{3}

Simplify

= \frac{26}{3}
