integral from-2 to 2 of sqrt(4-x)

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

46 - \frac{4 2}{3}

Decimal Notation

7.91234 \dots

Solution steps

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

Apply u-substitution

: \int_{6}^{2} - u d u

= \int_{6}^{2} - u d u

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

= - \int_{2}^{6} - u d u

Take the constant out:

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

= - (- \int_{2}^{6} u d u)

Apply the Power Rule

: [\frac{2}{3} u^{\frac{3}{2}}]_{2}^{6}

= - (- [\frac{2}{3} u^{\frac{3}{2}}]_{2}^{6})

Simplify

= [\frac{2}{3} u^{\frac{3}{2}}]_{2}^{6}

Compute the boundaries:

46 - \frac{4 2}{3}

= 46 - \frac{4 2}{3}

\int_{0}^{π} cos (2 t) d t

\int_{0}^{2} 2 y - y^{2} d y

\int_{1}^{5} \frac{7}{x} d x

\int_{0}^{2} 15 x^{2} + 14 x - 8 d x

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