integral from 0 to 1 of ssqrt(1-s^2)

\int_{0}^{1} s 1 - s^{2} d s

\frac{1}{3}

Decimal

0.33333 \dots

Solution steps

\int_{0}^{1} s 1 - s^{2} d s

Apply u-substitution

: \int_{1}^{0} - u^{2} d u

= \int_{1}^{0} - u^{2} d u

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

= - \int_{0}^{1} - u^{2} d u

Take the constant out:

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

= - (- \int_{0}^{1} u^{2} d u)

Apply the Power Rule

: [\frac{u ^{3}}{3}]_{0}^{1}

= - (- [\frac{u ^{3}}{3}]_{0}^{1})

Simplify

= [\frac{u ^{3}}{3}]_{0}^{1}

Compute the boundaries:

\frac{1}{3}

= \frac{1}{3}

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

\int_{1}^{2} 1 + \frac{x ^{3}}{8} d x

\int_{- 2}^{2} (x^{2} - 3) d x

\int_{0}^{t} 2 d x

\int_{1}^{2} x cos (nπ x) d x
