Entferne die Konstante:

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

= \frac{15}{2} \cdot \int_{0}^{1} 5 x + 4 d x

Wende U-Substitution an

= \frac{15}{2} \cdot \int_{4}^{9} \frac{u}{5} d u

Entferne die Konstante:

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

= \frac{15}{2} \cdot \frac{1}{5} \cdot \int_{4}^{9} u d u

Wende die Potenzregel an

= \frac{15}{2} \cdot \frac{1}{5} [\frac{2}{3} u^{\frac{3}{2}}]_{4}^{9}
