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

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

\frac{4 2}{3}

Decimal Notation

1.88561 \dots

Solution steps

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

Apply u-substitution

: \int_{2}^{0} - u d u

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

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

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

Take the constant out:

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

= - (- \int_{0}^{2} u d u)

Apply the Power Rule

: [\frac{2}{3} u^{\frac{3}{2}}]_{0}^{2}

= - (- [\frac{2}{3} u^{\frac{3}{2}}]_{0}^{2})

Simplify

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

Compute the boundaries:

\frac{4 2}{3}

= \frac{4 2}{3}

\int_{- 1}^{1} (x^{4} - x^{5}) d x

\int_{0}^{\frac{π}{2}} sec^{4} (\frac{x}{2}) d x

\int_{- 4}^{4} x^{2} - 16 d x

\int_{0}^{1} \frac{1}{3 x - 2} d x

\int_{- 4}^{0} - y - (y^{2} + 3 y) d y
