Schritte zur Lösung

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

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

= \frac{7}{3} + 2

Vereinfache

\frac{7}{3} + 2 : \frac{13}{3}

= \frac{13}{3}

\int_{- 2}^{2} x^{3} - 2 x^{2} + 7 d x

\int_{1}^{4} 8 d x

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

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

\int_{- 7}^{7} \frac{t ^{3}}{11 + 8 t ^{2}} d t
