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

\int_{0}^{\frac{π}{2}} cos (x) d x = 1

\int_{0}^{\frac{π}{2}} 1 d x = \frac{π}{2}

= 1 - \frac{π}{2}

\int_{- 1}^{1} (\frac{x ^{3} - 8}{x - 2}) d x

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

\int_{0.5}^{0} x d x

\int_{2}^{5} 6 x^{- 2} d x

\int_{4}^{7} e^{2 x + 1} d x
