Schritte zur Lösung

\int_{1}^{10} \frac{2}{81} (x - 1) d x

Entferne die Konstante:

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

= \frac{2}{81} \cdot \int_{1}^{10} x - 1 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

= \frac{2}{81} (\int_{1}^{10} x d x - \int_{1}^{10} 1 d x)

\int_{1}^{10} x d x = \frac{99}{2}

\int_{1}^{10} 1 d x = 9

= \frac{2}{81} (\frac{99}{2} - 9)

Vereinfache

\frac{2}{81} (\frac{99}{2} - 9) : 1

= 1

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

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

\int_{0}^{2} (4 x - 2) d x

\int_{- 4 π}^{π} cos^{2} (x) d x

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