Lösung

\int_{0}^{2 π} 3 cos (t) d t

0

Schritte zur Lösung

\int_{0}^{2 π} 3 cos (t) d t

Entferne die Konstante:

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

= 3 \cdot \int_{0}^{2 π} cos (t) d t

Nutze das gemeinsame Integral :

\int cos (t) d t = sin (t)

= 3 [sin (t)]_{0}^{2 π}

Berechne die Grenzen:

0

= 3 \cdot 0

= 0

\int_{- 1}^{1} 2 x^{2} + \frac{2}{3} d x

\int_{- 1}^{0} (x^{\frac{1}{3}} - x) d x

\int_{0}^{π} y sin (x) d x

\int_{- 1}^{2} x (\frac{x ^{2}}{3}) d x

\int_{- 1}^{1} \frac{x}{x + 2} d x
