\int_{- 2}^{- 1} \frac{1}{z} (y + \frac{1}{2}) d y

- \frac{1}{z}

Schritte zur Lösung

\int_{- 2}^{- 1} \frac{1}{z} (y + \frac{1}{2}) d y

Entferne die Konstante:

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

= \frac{1}{z} \cdot \int_{- 2}^{- 1} \frac{1}{2} + y d y

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \frac{1}{z} (\int_{- 2}^{- 1} \frac{1}{2} d y + \int_{- 2}^{- 1} y d y)

\int_{- 2}^{- 1} \frac{1}{2} d y = \frac{1}{2}

\int_{- 2}^{- 1} y d y = - \frac{3}{2}

= \frac{1}{z} (\frac{1}{2} - \frac{3}{2})

Vereinfache

\frac{1}{z} (\frac{1}{2} - \frac{3}{2}) : - \frac{1}{z}

= - \frac{1}{z}

\int_{- 4}^{- 1} (x^{3} + 5 x^{2} + 4 x) d x

\int_{2}^{6} 2400 x 3 + 2 x d x

\int_{1}^{2} 4 x^{3} - 6 x d x

\int_{0}^{2} 3^{x} - 4 d x

\int_{0}^{x} x^{2} + \frac{2}{y ^{2}} d y
