\int_{0}^{5} 5 ln (x) d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 5 \cdot \int_{0}^{5} ln (x) d x

Wende die partielle Integration an

= 5 [x ln (x) - \int 1 d x]_{0}^{5}

\int 1 d x = x

= 5 [x ln (x) - x]_{0}^{5}

Berechne die Grenzen:

5 ln (5) - 5

= 5 (5 ln (5) - 5)

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

\int_{0}^{2 π} cos^{4} (t) d t

\int_{0}^{\frac{π}{4}} cos (2 t) d t

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

\int_{0}^{3} (2 - x)^{2} d x
