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

Wende U-Substitution an

= \int_{0}^{3} u^{2} d u

Wende die Potenzregel an

= [\frac{u ^{3}}{3}]_{0}^{3}

Berechne die Grenzen:

= 3

\int_{0}^{\frac{7}{9}} \frac{1}{81 x ^{2} + 49} d x

\int_{x}^{5} cos (e^{t}) d t

\int_{1}^{3} \frac{1}{x - 1} d x

\int_{0}^{2} sin^{2} (x) d x

\int_{0}^{1} u d u
