Schritte zur Lösung

\int_{- 5}^{4} - x^{2} - 3 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

= - \int_{- 5}^{4} x^{2} d x - \int_{- 5}^{4} 3 x d x

\int_{- 5}^{4} x^{2} d x = 63

\int_{- 5}^{4} 3 x d x = - \frac{27}{2}

= - 63 - (- \frac{27}{2})

Vereinfache

- 63 - (- \frac{27}{2}) : - \frac{99}{2}

= - \frac{99}{2}

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

\int_{0}^{1} x cos (πn x) d x

\int_{0}^{\frac{1}{2}} ln (1 - x^{2}) d x

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

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