integral of 4cos(1-x)

Lösung

\int 4 cos (1 - x) d x

Lösung

- 4 sin (1 - x) + C

Schritte zur Lösung

\int 4 cos (1 - x) d x

Entferne die Konstante:

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

= 4 \cdot \int cos (1 - x) d x

Wende die partielle Integration an

= 4 (cos (1 - x) x - \int sin (1 - x) x d x)

\int sin (1 - x) x d x = x cos (1 - x) + sin (1 - x)

= 4 (cos (1 - x) x - (x cos (1 - x) + sin (1 - x)))

Vereinfache

4 (cos (1 - x) x - (x cos (1 - x) + sin (1 - x))) : - 4 sin (1 - x)

= - 4 sin (1 - x)
