Schritte zur Lösung

\int_{0}^{π} π - 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}^{π} π d x - \int_{0}^{π} x d x

\int_{0}^{π} π d x = π^{2}

\int_{0}^{π} x d x = \frac{π ^{2}}{2}

= π^{2} - \frac{π ^{2}}{2}

\int_{- 1}^{0} \frac{1}{4 x ^{2} - 9} d x

\int_{1}^{e^{x}} 4 ln (t) d t

\int_{- 3}^{5} (4 x - 3)^{3} d x

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

\int_{- 2}^{- 1} \frac{1}{( 11 + 5 x ) ^{3}} d x
