integral from 0 to t of sin(w(t-x))

Lösung

\int_{0}^{t} sin (w (t - x)) d x

- \frac{- 1 + cos ( wt )}{w}

Schritte zur Lösung

\int_{0}^{t} sin (w (t - x)) d x

Wende U-Substitution an

= \int_{t}^{0} - sin (w u) d u

Entferne die Konstante:

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

= - \int_{t}^{0} sin (w u) d u

Wende U-Substitution an

= - \int_{wt}^{0} \frac{sin ( v )}{w} d v

Entferne die Konstante:

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

= - \frac{1}{w} \cdot \int_{wt}^{0} sin (v) d v

Nutze das gemeinsame Integral :

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

= - \frac{1}{w} [- cos (v)]_{wt}^{0}

Berechne die Grenzen:

- 1 + cos (wt)

= - \frac{1}{w} (- 1 + cos (wt))
