Schritte zur Lösung

\int_{3}^{7} \frac{9}{x} + 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_{3}^{7} \frac{9}{x} d x + \int_{3}^{7} 3 x d x

\int_{3}^{7} \frac{9}{x} d x = 9 (ln (7) - ln (3))

\int_{3}^{7} 3 x d x = 60

= 9 (ln (7) - ln (3)) + 60

\int_{0}^{3} \frac{x}{x ^{2} + 3} d x

\int_{2}^{\infty} 6 x d x

\int_{0}^{2 π} 2 sin^{2} (θ) d θ

\int_{0}^{1} (x - 2)^{2} d x

\int_{0}^{12} 8 x d x
