\int_{- \frac{π}{2}}^{\frac{π}{2}} cos (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_{- \frac{π}{2}}^{\frac{π}{2}} cos (x) d x - \int_{- \frac{π}{2}}^{\frac{π}{2}} 5 d x

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

\int_{- \frac{π}{2}}^{\frac{π}{2}} 5 d x = 5 π

= 2 - 5 π

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

\int_{- 7}^{7} 4 x - 3 d x

\int_{0}^{3} e^{- \frac{1}{2} t} d t

\int_{- 5}^{5} \frac{7}{x ^{3}} d x

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