integral from 1 to 5 of k(5-x)

Lösung

\int_{1}^{5} k (5 - x) d x

8 k

Schritte zur Lösung

\int_{1}^{5} k (5 - x) d x

Entferne die Konstante:

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

= k \cdot \int_{1}^{5} 5 - x 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

= k (\int_{1}^{5} 5 d x - \int_{1}^{5} x d x)

\int_{1}^{5} 5 d x = 20

\int_{1}^{5} x d x = 12

= k (20 - 12)

= 8 k

\int_{0}^{2} (x + 1)^{\frac{2}{3}} d x

\int_{2}^{4} - 4 x^{3} ln (x) d x

\int_{0}^{\frac{π}{2}} sin (x^{3}) d x

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

\int_{0}^{1} 2^{x + 1} d x
