0.31640625

Schritte zur Lösung

\int_{0.5}^{2} 0.09375 (4 - x^{2}) d x

Entferne die Konstante:

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

= 0.09375 \cdot \int_{0.5}^{2} 4 - 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

= 0.09375 (\int_{0.5}^{2} 4 d x - \int_{0.5}^{2} x^{2} d x)

\int_{0.5}^{2} 4 d x = 6

\int_{0.5}^{2} x^{2} d x = 2.625

= 0.09375 (6 - 2.625)

= 0.31640625

\int_{- 4}^{- 1} - \frac{4}{x} + 4 x d x

\int_{1}^{2} x^{3} 9 + x^{2} d x

\int_{0}^{6} \frac{1}{( 2 x + 7 ) ^{2}} d x

\int_{0}^{3} (1 + 9 - x^{2}) d x

\int_{0}^{2 π} (1 + cos (x)) d x
