integral from 0 to 4 of sqrt(x-1)

\int_{0}^{4} x - 1 d x

23 + \frac{2 i}{3}

Solution steps

\int_{0}^{4} x - 1 d x

Apply u-substitution

= \int_{- 1}^{3} u d u

Apply the Power Rule

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

Compute the boundaries:

23 + i \frac{2}{3}

= 23 + i \frac{2}{3}

Simplify

= 23 + \frac{2 i}{3}
