integral from 0 to pi of cos^2(x)sin(x)

Lösung

\int_{0}^{π} cos^{2} (x) sin (x) d x

Lösung

\frac{2}{3}

+1

Dezimale

0.66666 \dots

Schritte zur Lösung

\int_{0}^{π} cos^{2} (x) sin (x) d x

Wende U-Substitution an

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

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

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

Entferne die Konstante:

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

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

Wende die Potenzregel an

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

Vereinfache

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

Berechne die Grenzen:

\frac{2}{3}

= \frac{2}{3}
