Schritte zur Lösung

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

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

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

Wende die Potenzregel an

= - [- \frac{1}{x}]_{1}^{2}

Berechne die Grenzen:

\frac{1}{2}

= - \frac{1}{2}

\int_{0}^{3} \frac{x}{1 + x} d x

\int_{2}^{3} (x^{2} + x - 12) d x

\int_{0}^{π} sin (x) sin (6 x) d x

\int_{0}^{t} 2 x d x

\int_{0}^{0.7} ln (x^{2} + 1) d x
