integral from 0 to 1-cos(θ) of (sin(θ))r

Lösung

\int_{0}^{1 - c o s (θ)} (sin (θ)) r d r

\frac{sin ( θ ) ( - cos ( θ ) + 1 ) ^{2}}{2}

Schritte zur Lösung

\int_{0}^{1 - c o s (θ)} sin (θ) r d r

Entferne die Konstante:

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

= sin (θ) \cdot \int_{0}^{1 - c o s (θ)} r d r

Wende die Potenzregel an

= sin (θ) [\frac{r ^{2}}{2}]_{0}^{1 - c o s (θ)}

Berechne die Grenzen:

\frac{( - cos ( θ ) + 1 ) ^{2}}{2}

= sin (θ) \frac{( - cos ( θ ) + 1 ) ^{2}}{2}

Vereinfache

= \frac{sin ( θ ) ( - cos ( θ ) + 1 ) ^{2}}{2}
