\int_{0}^{π} 2 π x sin (x) d x

Entferne die Konstante:

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

= 2 π \cdot \int_{0}^{π} x sin (x) d x

Wende die partielle Integration an

= 2 π [- x cos (x) - \int - cos (x) d x]_{0}^{π}

\int - cos (x) d x = - sin (x)

= 2 π [- x cos (x) - (- sin (x))]_{0}^{π}

Vereinfache

= 2 π [- x cos (x) + sin (x)]_{0}^{π}
