integral from 1 to 3 of (x^2+2x-3)

Lösung

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

Lösung

\frac{32}{3}

+1

Dezimale

10.66666 \dots

Schritte zur Lösung

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

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int_{1}^{3} x^{2} d x = \frac{26}{3}

\int_{1}^{3} 2 x d x = 8

\int_{1}^{3} 3 d x = 6

= \frac{26}{3} + 8 - 6

Vereinfache

\frac{26}{3} + 8 - 6 : \frac{32}{3}

= \frac{32}{3}
