\int_{0}^{3 π} 1 + cos (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_{0}^{3 π} 1 d x + \int_{0}^{3 π} cos (x) d x

\int_{0}^{3 π} 1 d x = 3 π

\int_{0}^{3 π} cos (x) d x = 0

= 3 π + 0

Vereinfache

= 3 π

\int_{0}^{0.8} x e^{x} d x

\int_{0}^{1} (\frac{1}{1 + x}) d x

\int_{0}^{1} \frac{32}{x ^{2} - 16} d x

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

\int_{- 7}^{6} - 2 y^{3} - y^{2} + 36 d y
