integral from-1 to 5 of 4x-x^2+5

Lösung

\int_{- 1}^{5} 4 x - x^{2} + 5 d x

36

Schritte zur Lösung

\int_{- 1}^{5} 4 x - x^{2} + 5 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} 4 x d x - \int_{- 1}^{5} x^{2} d x + \int_{- 1}^{5} 5 d x

\int_{- 1}^{5} 4 x d x = 48

\int_{- 1}^{5} x^{2} d x = 42

\int_{- 1}^{5} 5 d x = 30

= 48 - 42 + 30

= 36
