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

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

\frac{4 2 - 2}{3}

Decimal

1.21895 \dots

Solution steps

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

Apply u-substitution

= \int_{2}^{1} - u d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{1}^{2} - u d u

Take the constant out:

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

= - (- \int_{1}^{2} u d u)

Apply the Power Rule

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

Simplify

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

Compute the boundaries:

\frac{4 2}{3} - \frac{2}{3}

= \frac{4 2}{3} - \frac{2}{3}

Simplify

= \frac{4 2 - 2}{3}
