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

Wende U-Substitution an

= \int_{2}^{5} u^{2} d u

Wende die Potenzregel an

= [\frac{u ^{3}}{3}]_{2}^{5}

Berechne die Grenzen:

\frac{5 5 - 2 2}{3}

= \frac{5 5 - 2 2}{3}

\int_{0}^{π} (1 + cos (θ))^{2} d θ

\int_{- 1}^{1} sin (nπ x) d x

\int_{1}^{9} 6 x - 5 d x

\int_{2}^{5} 2^{5 x} d x

\int_{1}^{x^{2}} \frac{1}{t ^{4}} d t
