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}^{2} 4 x^{5} d x

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

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

\int_{0}^{\frac{π}{3}} sin (3 y) cos (y) d y

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