integral from 0 to pi of (1-sin^3(x))

\int_{0}^{π} (1 - sin^{3} (x)) d x

π - \frac{4}{3}

Decimal

1.80825 \dots

Solution steps

\int_{0}^{π} 1 - sin^{3} (x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{π} 1 d x - \int_{0}^{π} sin^{3} (x) d x

\int_{0}^{π} 1 d x = π

\int_{0}^{π} sin^{3} (x) d x = \frac{4}{3}

= π - \frac{4}{3}
