integral from 0 to 1 of xsqrt(4-x^2)

\int_{0}^{1} x 4 - x^{2} d x

\frac{8 - 3 3}{3}

Decimal Notation

0.93461 \dots

Solution steps

\int_{0}^{1} x 4 - x^{2} d x

Apply u-substitution

: \int_{4}^{3} - \frac{u}{2} d u

= \int_{4}^{3} - \frac{u}{2} d u

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

= - \int_{3}^{4} - \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_{3}^{4} u d u)

Apply the Power Rule

: [\frac{2}{3} u^{\frac{3}{2}}]_{3}^{4}

= - (- \frac{1}{2} [\frac{2}{3} u^{\frac{3}{2}}]_{3}^{4})

Simplify

= \frac{1}{2} [\frac{2}{3} u^{\frac{3}{2}}]_{3}^{4}

Compute the boundaries:

\frac{16}{3} - 23

= \frac{1}{2} (\frac{16}{3} - 23)

Simplify

= \frac{8 - 3 3}{3}

\int (x^{2} + 3 x - 1)^{4} (2 x + 3) d x

f (x) = 5 csc^{4} (x)

1000 (1 + \frac{r}{12})^{60}

n = 1 \sum \infty \frac{1}{2}

1 - e^{- s}
