Lösung

\int_{1}^{2} 2 x + 5 d x

8

Schritte zur Lösung

\int_{1}^{2} 2 x + 5 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} 2 x d x + \int_{1}^{2} 5 d x

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

\int_{1}^{2} 5 d x = 5

= 3 + 5

Vereinfache

= 8

\int_{1}^{6} 2 x + \frac{1}{x} d x

\int_{- \frac{π}{6}}^{\frac{π}{6}} 2 sec^{2} (x) d x

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

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

\int_{0}^{6} x - 3 d x
