integral of 5xcos(x)

Lösung

\int 5 x cos (x) d x

5 (x sin (x) + cos (x)) + C

Schritte zur Lösung

\int 5 x cos (x) d x

Entferne die Konstante:

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

= 5 \cdot \int x cos (x) d x

Wende die partielle Integration an

= 5 (x sin (x) - \int sin (x) d x)

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

= 5 (x sin (x) - (- cos (x)))

Vereinfache

= 5 (x sin (x) + cos (x))
