Schritte zur Lösung

\int_{0}^{1} - 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_{0}^{1} x^{2} d x - \int_{0}^{1} 3 x d x

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} 3 x d x = \frac{3}{2}

= - \frac{1}{3} - \frac{3}{2}

Vereinfache

- \frac{1}{3} - \frac{3}{2} : - \frac{11}{6}

= - \frac{11}{6}

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

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

\int_{4}^{7} (2 x + 1) e^{0.4 x} d x

\int_{0}^{l o g_{3} (5)} 3^{x} d x

\int_{0}^{2} \frac{6 x ^{2}}{2 + x ^{3}} d x
