integral from 1 to 5 of (2+3x-x^2)

Lösung

\int_{1}^{5} (2 + 3 x - x^{2}) d x

Lösung

\frac{8}{3}

+1

Dezimale

2.66666 \dots

Schritte zur Lösung

\int_{1}^{5} 2 + 3 x - x^{2} 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}^{5} 2 d x + \int_{1}^{5} 3 x d x - \int_{1}^{5} x^{2} d x

\int_{1}^{5} 2 d x = 8

\int_{1}^{5} 3 x d x = 36

\int_{1}^{5} x^{2} d x = \frac{124}{3}

= 8 + 36 - \frac{124}{3}

Vereinfache

8 + 36 - \frac{124}{3} : \frac{8}{3}

= \frac{8}{3}
